PROBLEM 1. Compute stress, strain and displacement at point A (x,y). Given: Elastic domain, E= 10 Mpa, v= 0.3 x= 4, y= 1.42 Fx= 47, Fy= 182.5 Each element is a 5x5 constant strain triangle, the domain spreads -5m to 5m in x direction and 0 to 5 m in y direction. Use Finite Element Method to calculate deformations, strain and stress at point A (x,y). F (Fx,Fy) y A (x,y) X Now, compute the following: a) the element stiffness matrices for the 2 elements b) the global stiffness matrix c) displacements of the 4 nodes of the elements d) displacement at point A e) strain at point A f) stress at point A Use Matlab software for the calculations.
