Development of an Interactive Finite Element Solution Module for 2d Stress Problem Analysis Using Isoparametric Element
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 4
Abstract
Finite Element Method Has Been Established As One Of The Most Versatile Tool Commonly Employ In Solving Complex Engineering Problems. In This Work, Finite Element Analysis Module For Stress Problem Using Isoparametric Element Was Developed And Utilized In Some Selected Engineering Problems. TwoDimensional Standard Deflection (Flexural) Equation Was Used In The Modelling. Isoparametric 8-Noded Element With 16 Degree Of Freedom Was Also Adopted In The Model. The Domain Was Discretized Into Six And Nine Elements For The Cases Analyzed. Matlab Code Was Written Based On The Developed Model. Graphic User Interface (Gui) Was Also Developed In Other To Make The Analysis Easier For The User. A Windows Application Was Created From Matlab Standalone App In Gui For Easy Access Of The Module. Case Studies For Curvilinear Structural Element Were Used To Test-Run The Developed Program. Windows Application Was Then Run With The Required Input Data. Global Displacement Were Obtained For Each Nodal Element (For Case One, Node 8 Experienced - 0.3371m And - 0.6663m In X And Y Direction, Respectively While For Case Two, Node 8 Experienced - 0.021m And 0.14m, Respectively). Also, The Global Node Reactions Were Obtained For Each Nodal Element (For Case One, Node 8 Experienced Nodal Reactions Of -29.07kn And 19.98kn In X And Y Direction, While For Case Two, Node 8 Experienced Nodal Reactions Of 2.6kn And 9.7kn, Respectively). Stresses For Each Element (Case One, Element One Experienced 1.81kn/M, 21.28kn/M And -3.36kn/M And For Case Two, Element One Experienced -6.32kn/M, -5.64kn/M And - 12.08kn/M). Developed Finite Element Analysis Module For Stress Problem Using Isoparametric Element Established An Improvement Over Previous Result Obtained From The Same Case Studied; Hence The Module Can Be Used For Other Related Problems.
