For this work, an user-defined element (UEL) in ABAQUS was developed in conjunction with a triangular traction separation law, as the Cohesive Zone Model, that combines the Extended Finite Element and Cohesive Element ...

In this work, we focus our attention on initiation and progressive damage of isotropic and composite structures using Strain Invariant Failure Theory (SIFT) at the micro-level. The stress-based tools are very popular to ...

Aluminum based metal matrix composites are finding many applications in engineering. Of these Al-Al2O3 composites appear to have promise in a number of defense applications because of their mechanical properties. However, ...
