000012403 520__ $$2eng$$aTwo Drucker-Prager criteria are employed to define a nonlinear material model for concrete that is capable to solve tri-axial analysis of plasticity. The model consists of one Drucker-Prager criterion set to approximate tensile stress area and the other to describe compression area. The first derivative singularities are treated by using an imaginary tangent as a local yield function and the model is modified for specific application for the plane stress state. The model is implemented into the SIFEL solver using the finite element method.
