Question

Write a computer program (preferably in MatLAB) to solve the following bar problem using finite element method. As shown in the figure below, the bar is fixed at the left and right ends. It is subjected to two forces as shown in the figure. The input to the code should be Material properties (Modulus of elasticity). 2. I. Length of the bar, L 3. Magnitudes and locations of Fi and F2 4. Number of elements. Output of the finite element code should be: I. Displacement at each node. 2. Reaction forces of the supports 3. Strain at each element. 4. Stress at each element. Make a case study to investigate the effect of distance, d, between Fi and F2 on the value of maximum stress in the bar. Please note that the stress in the bar should not exceed the yield strength of the material and strain should be less than 0.2%.
