WebJan 23, 2024 · The CDP model captures two features: plasticity and damage mechanics with characteristic failure modes (i.e., cracking in tension and crushing in compression). The CDP model is examined to assess its ability to capture the mechanical response of mortar, brick and concrete. WebA plastic damage model based on tension tests was established to further analyze damage evolution during reduction pretreatment. Experimental results showed that the distribution of the damage was characterized by microvoids near the surface and microcracks along the grain boundary at the center. With the increase in strain rate, …

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. WebIn Grassl and Jirásek (2006), the main framework of the present damage plasticity model was developed, which was called CDPM. In this work an effective stress based plasticity model was combined with a scalar damage approach with one damage variable for both tension and compression.
