A phenomenological model of damage in articular cartilage under impact loading

• Damage progression in high-strain rate and impact tests on articular cartilage is considered.
• A new type of kinetic damage evolution law is proposed.
• Based on the developed damage model, a new fracture criterion is introduced.

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.
