文摘

We present an approach for obtaining damage variables for Plastic Damage Models. Approach is suitable for describing monotonic behavior of RC structures. Advantages: mesh-insensitive, continuum mechanics-based, no calibration required. A particular algorithm is presented and implemented in Abaqus.
