Signiﬁcant progress has been made on computational contact mechanics over the past decade. Many of the drawbacks that were inherent to the standard node-tosegment element strategy, such as locking/over-constraint and non-physical jumps in the conta

This contribution describes the numerical treatment and calibration strategy for a new micromechanical damage model, which employs two internal damage variables. The new micromechanical model is based on Gurson's theory incorporating the void volume
