MECH0059 Write a MATLAB program to determine the displacement and strain in the thin plate shown in Figure 1A: FEA Assignment, UCL, UK

THE PROBLEM
Use the finite element method to carry out a strain/stress analysis of the 2D structure shown in Figure 1A (under plane stress condition). Use the following parameters: E=40 GPa, v=0.3, and plate thickness of 2 mm.

Part 1: Write a MATLAB program to determine the displacement and strain in the thin plate shown in Figure 1A, consisting of 4 noded quadrilateral elements (see Figure 1B), under uniform tension. Please use any arrangement and number of elements that you would like to (You may consider using three elements). Note that you must consider the “L” based on the first letter of your family name (see Figure IC).

MECH0059 Re-run your program in Part 1 to determine the displacement and strain: FEA Assignment, UCL, UK

Part 2: Re-run your program in Part 1 to determine the displacement and strain, (i) for three additional elastic moduli (ii) for three additional loading conditions i.e. changing the loading direction from O=90°. Keep other variables constant. Here compare the results of the additional simulations performed.

Part 3: use ANSYS Mechanical APDL to: (i) validate the MATLAB program, and (ii) carry out mesh convergence, for a specific configuration of your choice (in terms of elastic modulus and loading condition).
