| Abstract: | Damage progression in high-strain rate and impact tests on articular cartilage is considered. A new type of kinetic damage evolution law is proposed and used to draw implications about the accumulated damage and the coefficient of restitution. Based on the developed damage model, a new fracture criterion is introduced. |
