Simulations are carried out to determine the magnitude of displacements, strains and stresses based on the materials and materials, constraints, and loads given.
Reducing the risk of errors in material selection can have an effect on production costs where production costs can decrease because materials can be used as much as possible or according to capacity.
When simulating stress analysis there are several steps that must be considered such as selecting materials, determining constraints, and determining loads.

Basic Theory The yield criterion of materials is the Drucker-Prager criterion - the yield cone surface is through outside vertices of yield hexagon in the following calculations. plastic flow rule is the orthogonal flow rule. the yield function of Drucker-Prager model is (1) Where , = parameter of material, = the first stress tensor invariant, = the second stress tensor invariant.
The stress-strain relations for a material that has cracked in one direction only become: (7) If the crack closes, then all compressive stresses normal to the crack plane are transmitted across the crack and only a shear transfer coefficient βc for a closed crack is introduced.
