Nettet1. jan. 2024 · Concrete damaged plasticity (CDP) model is one of the most popular material models for plain and reinforced concrete implemented in Abaqus software. It is theoretically described by Lubliner et al. and Lee and Fenves. Use of this model requires values of some material constants. The choice of proper values of these constants is … NettetDamage is modeled as the functions of plastic strain following Lee and Fenves (1998). 2 PLASTICITY FORMULATION Three parameter Menetrey-William type yield function (in the effective stress space) with multiple hardening parameters is chosen to define plastic loading of the material.

It has been proved that for monotonic loading, the damage variable has marginal effects (Lee and Fenves 1998, Hany et al. 2016, Mohammadi and Wu 2024 ). Hence the damage is assumed to be zero for simplicity. dinta by chioma
