Damage plasticity model for concrete #184
Description
Reason
Lee and Fenves model for concrete decouple the effect of plasticity and damage in concrete. It helps in studying the reinforcement concrete structure for a variety of loading with the evolution of the damage variable with plasticity.
Design
The calculation is performed in the effective stress space and then the state of stress return back to the stress space using (1-D) factor.
Impact
Damage-plasticity model is one of the popular models which is frequently used for the analysis of concrete structures.
