The finite element method is used to solve the plate with uniformly tensioned edges

The problem of plane stress is solved , That is, the plate with uniform force on the edge . Use isoparametric Q4 Element discretizes the plate . standards-of-use FEM Software preprocessing . The second order Gauss integral is used to obtain the stiffness matrix . Compare the results obtained with the standard FEM Software for comparison , The two results are in good agreement .
