Damaged plasticity model
WebThe concrete damage plasticity model, is an isotropic model derived from the Drucker Prager yield criterion. It requires linear elasticity for the first part of the stress-strain relationship, that can be assigned by providing the Young's modulus and Poisson's ratio. WebA quasi-static, isothermal damage model based on a ductile failure criterion was implemented in the finite element analysis to simulate the removal of the fully damaged elements. Numerical results illuminate the effects of the load and coefficient of friction on the development of plasticity, cumulative damage, and loss of material with ...
