What are the best values of concrete damage plasticity parameters that can be used for RC shear walls analysis by abaqus ?
The parameters are the ratio of initial equibiaxial compressive yield stress to initial uniaxial compressive yield stress(1.16) and the ratio of the second
deviatoric stress invariant on the tensile meridian to that on compression
meridian (Kc=0.67). The eccentricity parameter associated with the flow potential is assumed to be 0.1. dilation angle = 55 degree
Dear Haider:
Chapters 3 and 4 of the attached thesis may be of interest to you.

Dear Haider Sakban and other colleagues,
The following paper is a very good reference. It is a very current methodology.
- B. Alfarah, F. López-Almansa, S. Oller, New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures, Engineering Structures. 132 (2017) 70–86.
