ANALYSIS OF BUCKLING AND POSTBUCKLING LOADS OF ISOTROPIC THIN RECTANGULAR PLATES

AUTHOR: OGUAGHAMBA, ONYEDIKACHI ALOYSIUS (PhD)

DEPARTMENT: Civil Engineering

SCHOOL: School of Engineering and Engineering Technology (SEET)

AFFILIATION: Federal University of Technology Owerri

This study investigated the analysis of buckling and postbuckling loads of isotropic thin rectangular plates. The study derived the governing differential equations defining the postbuckling behaviour of isotropic thin rectangular plates, known as von Karman’s equilibrium and compatibility large deflection equations; as well as the governing differential equation of plates’ buckling. In view of the complex nature of these equations, it is not possible to obtain their closed-form solutions. Hence, the study used the direct integration method to solve the governing differential equation of plates’ buckling and the von Karman’s compatibility large deflection equation of plates to obtain their deflections and stresses functions respectively for different support conditions. Then, the study applied these functions in the von Karman’s equilibrium large deflection equation to solve for the buckling and postbuckling loads of these plates using work principle technique. The displacement parameters, Wuv, stress coefficients, Wuv2 and load factors, Kcx for the various support conditions of plates were determined using the Johasen yield line theory, leading to the critical buckling and postbuckling loads and stresses of these plates. The study’s numerical analysis among other things revealed that thin rectangular plates possess postbuckling reserve of strength upon buckling. That is, they do not fail at mere critical buckling loads. Their postbuckling reserve of strength upon buckling loads are due to the transverse and longitudinal fibers of the plates which undergo stress redistribution with consequential tensile stress build up in the plates. Another finding of the study is that plates’ reduction in axial stiffness upon buckling is due to the in-plane load postbuckling bending stresses developed in the plates, in the cause of buckling. These bending stresses lower the axial stiffness of plates. Other revelation of the study is that plates would reach yield stress at different out of plane deflections, depending on their support conditions. SSSS, CCCC, CSCS, CSSS, CCSS, CCSC, SCFC and CCFC, plates reach yield stress at out of plane deflection coefficient of 4.1, 0.1, 1.4, 3.1, 1.8, 1.1, 3.0, and 2.80 of their plates’ thicknesses, h respectively. These group of thin rectangular plates could be adequately be designed for in – plane loads using their critical buckling and postbuckling loads and stresses. While SSFS, CSFS and SCFS plates possess yield stresses far below the yield stress of steel material (250MPa), even at 5.0h out of plane deflection. In the design of such plates, the deflections criteria should be implored as their yield stresses would result to inadmissible deflections. This study has made useful contribution towards solving the problem of dearth of literature on the analysis of buckling and postbuckling loads of isotropic thin rectangular plates, especially with regard to the use of direct integration method and work principle to solve these differential equations. Other novel feat of the study is the use of Johasen yield line theory to deduce the displacement parameters, Wuv, stress coefficients, Wuv2 and load factors, Kcx for the various support conditions of thin rectangular plates.

ACHIEVING EXCELLENCE IN RESEARCH PUBLICATION IN INDEXED JOURNALS BY CRID FUTO

The Centre for Research and International Development of the Federal University of Technology Owerri organized a one-day Workshop on “Achieving Excellence in Research Publication in Indexed Journals” for all teaching staff of the University. The primary goal of the workshop is to enlighten FUTO academics on the importance of publishing in classified and indexed journals which will ultimately boost the ranking of the staff and University.

This workshop was marked with the large turn out of academic staff members of FUTO in which three resource persons presented papers on:

AUTHOR: Prof. Oguzie, Emeka E.

PAPER PRESENTED: Publishing Aright to Elevate Your Research Impact and Ranking

AUTHOR: Prof. Ohajianya, Donatus O.

PAPER PRESENTED: Determinants of Choice and Right Journals for Publication of              Research Works

AUTHOR: Engr. Dr. Uzoechi, Lazarus O.

PAPER PRESENTED: Good Thinking Good Product Good Publication

PUBLISH ARIGHT –
ELEVATE YOUR RESEARCH IMPACT & RANKING

PROF. EMEKA E. OGUZIE, PROFESSOR OF ELECTROCHEMISTRY & MATERIALS SCIENCE. DEAN, SCHOOL OF ENVIRONMENTAL SCIENCES, FUTO

  • Research discovers, elucidates & evaluates new knowledge, ideas & the technologies essential in driving the future of society & humanity.
  • Nationally & internationally, our research activities & services have critical economic, societal & environmental impacts.
  • Research must always be high quality & research developments are critical in stimulating economic growth in knowledge economies.

It is equally important to have the perseverance to publish your research findings in reputable journals that are well regarded in your field….where people you admire in your field are publishing

PRESENTATION OUTLINE

  • Journal Impact
  • Research Impact
  • Author Impact
  • Publishing Aright
  • Broadening Your Impact

JOURNAL IMPACT FACTOR:

  • The impact factor of a journal is a measure of the frequency with which the

average article in the journal has been cited within the two preceding years.

  • It is a measure of the importance/rank of a journal by computing how many

times articles from the journal are cited.

  • It is a ratio between citations and recent citable items published

Calculation of 2017 Impact Factor of a journal:

X = the number of times articles published in 2015 and 2016 were cited by

indexed journals during 2017

B = the total number of “citable items” published in 2015 and 2016.

2017 impact factor = X/Y. Journal impact factor is used for 1. Journal Evaluation, Market research: Quantitative evidence of journal performance w.r.t others in the same field  Marketing/advertising tool to attract authors, hence improve readership 2. Academic evaluation  JIF is widely used for approximating the prestige of the journals in which researchers have been published. Other important factors like peer review, productivity, individual citation counts and subject specialty must also be considered. Hence JIF should not be used as a short-cut to circumvent proper appraisal.

RESEARCH IMPACT

Research impact is the demonstrable contribution that excellent research makes to academia, society and the economy‘… Research Councils UK. “… when the knowledge generated by our research contributes to, benefits and influences society, culture, our environment and the economy”… University of York Research Impact Statement. “RESEARCH FOR DEVELOPMENT” (R4D). Prof. F.C Eze (VC, FUTO).

AUTHOR IMPACT

 

Publication in a high impact factor journal was traditionally regarded as a key indicator of research (and researcher) quality.

Contemporary Considerations

  • Impact factor of publications
  • Total number of papers
  • Total number of citations

Publishing in High-Impact Factor Journals

  • Your research idea needs to be good and original.  Select a real challenging problem whose solution significantly impacts on the domain. Formulate the problem in such a way that reviewers see the significance of the problem.
  • Propose a solution with high degree of novelty in a way that has not been undertaken before for the same problem.
  • Select your journal carefully, follow the instructions for authors and read several papers from that journal, paying attention to the structure and language of the papers.
  • Imagine your research as telling a story. Start by asking a big question, and form a logical argument.
  • Throughout the research try to follow the conventions of research in your domain in the highest possible level, especially when it comes to evaluation and validation of your work.
  • In data collection phase, try to follow the most appropriate approaches and use accurate tools
  • Be topical. High IF journals are also businesses and will favour topics which catch the attention of a wider readership.
  • High-impact journals favour research with broad relevance, so  your writing should not be strictly for experts in your field.
  • It is essential that you have a good grasp of the research which has already been done in your area.
  •  You need some good luck, since high IF journals are very selective and competitive, with acceptance rate between 7% and 25%. For instance, of the 11,000 articles submitted to Nature in 2014, only 856 (7.8%) were published.
  • Given the low acceptance rate of many of these journals, you need to be tough enough to accept rejection letters – which will undoubtedly come your way.
  • Keep trying until you break-in

BROADENING YOUR IMPACT

Social network for scientists enable sharing of research, collaboration, and some altmetrics.

Academia.edu: A platform created to allow researchers to share their research. Researchers in all disciplines can share their work and ‘follow’ others in their field.

LinkedIn: A popular social networking tool for professionals in all fields. A LinkedIn profile is similar to an online CV, and makes finding people in particular fields of work or with particular affiliations easier.

Mendeley: Primarily known as a citation management tool, Mendeley includes a social networking element that allows the sharing of research libraries and tracks downloads and views as an alternative research impact measurement.

ResearchGate: Similar to Academia.edu, this platform facilitates sharing of research and collaboration with other researchers in your field.

Raadaa.com: Online Research Collation Platform (a Nigerian initiative). Find, read, write and share interesting research content.

USE OF MODIFIED SWEET POTATO STARCHES AS CORROSION INHIBITORS OF SELECTED METALS

AUTHOR: ANYIAM,CHIOMA KEZAIAH (PhD)

DEPARTMENT: Polymer and Textile Engineering

SCHOOL: School of Engineering and Engineering Technology (SEET)

AFFILIATION: Federal University of Technology Owerri

Sweet potato starch was modified via extrusion, alkaline steeping and acid steeping to yield physically modified starch (PMS), alkaline treated sweet potato starch (ASS) and acid treated sweet potato starch (ATS). The unmodified and modified starches were characterized using the Fourier transform infrared spectroscopy and assessed for corrosion inhibition efficacy on mild steel and galvanised steel in 0.25 M H2SO4 and 1 M HCl using gravimetric (weight loss) measurements and potentiodynamic polarization techniques. All the starch samples inhibited corrosion of the metals in the acidic media, with maximum efficiency ranging from 22.86 to 62.76 % for mild steel and 24.27 to 63.48 % for galvanised steel. Introduction of potassium iodide notably increased inhibition efficiency up to 85.59 %, 85.09 %, 83.64 %, 87.72 % for NS, PMS, ASS, and ATS respectively for mild steel and for galvanised steel 92.60 %, 95.62 %, 93.67 % and 93.94 % respectively for NS, PMS, ASS and ATS. Fourier transform infrared spectroscopy was used to analyse the scrapped metal after corrosion in presence and absence of the additives in the acidic media. Atomic force microscopy was used to analyse the surface morphology of the corroded metals in the presence and absence of the additives in the acidic media. The inhibitor adsorption characteristics were found to obey Langmuir isotherms. Temperature studies (30-60OC) investigated showed higher inhibition efficacy at lowest temperatures, thus suggesting physiosorption adsorption mechanism. These results were in agreement with the kinetic and activation energy parameters investigated. Potentiodynamic polarization measurements showed that NS, PMS, ASS and ATS are mixed-type inhibitors.
