Rate-dependent Damage Evolution and its Influence on Dynamic Behavior of Materials at High Strain Rates
damage evolution dynamic behavior of materials high strain rate adiabatic shearing
2012/9/24
Both experimental and numerical results reveal that dynamic damage evolution depend s on both strain and strain rate. Based on the thermal activ ated mechanism, a new damage evolution law and a new...
Time-scale invariances in preseismic electromagnetic radiation,magnetization and damage evolution of rocks
Time-scale invariances preseismic electromagnetic radiation magnetization damage evolution
