Finite Element Methods for Stress Analysis (Ver. 2020/21) A2 - 1 MECHGM0059: Advanced Computer Applications in Engineering Finite Element Analysis - Assignment 2 THE PROBLEM Develop a finite element program based on 4 noded quadrilateral elements, using MATLAB to estimate the deformation of the structure shown in Figure 1A. Part 1: Write a MATLAB program to calculate the stiffness matrix of a two-dimensional plane stress 4 noded quadrilateral element as shown in Figure 1B. Assume E=200 GPa, ʋ=0.3 and plate thickness is 2 mm. Part 2: Use your program in Part 1 to determine the displacement and strain in Figure 1A, consisted of 2 and 4 quadrilateral elements. Assume E=200 GPa, ʋ=0.3 and plate thickness of 2 mm. Note do not change the dimensions in Figure 1 and use the element arrangement that you think is most appropriate. Part 3: Re-run your program in Part 2 to determine the displacement and strain, (i) for three additional elastic modulus (ii) for three additional loading conditions i.e. changing the loading direction from θ=90°. Keep other variables constant. Your report must compare/comment on the: • displacement and strain results obtained from different elements, material properties and loading conditions • validity of your program, here you are expected to model the same structure using a commercial program and compare your results against it. Figure 1: (A) A thin plate loaded. (B) a single four-noded element.
