Simulating spatial and temporal evolution of multiple wing cracks around faults in crystalline basement rocks [PDF]

, 2007
Fault zones are structurally highly spatially heterogeneous and hence extremely complex. Observations of fluid flow through fault zones over several scales show that this structural complexity is reflected in the hydrogeological properties of faults ...

Fatigue damage and stiffness evolution in composite laminates: a damage-based framework

Procedia Engineering, 2018
Abstract A damage-based design procedure has been developed by the authors to predict the damage evolution and the stiffness degradation in polymeric composite laminates under fatigue loading. For a safe and reliable design against fatigue degradation and failure, the initiation of the main damage mechanisms (off-axis cracks, delamination and fiber ...
