Tensile Failure of Composites: Influence of Interface and Matrix Yielding

Yielding stress of matrix and interface is chosen to represent the influence of the chemical, mechanical, and thermodynamical nature of the bonding process between matrix and fiber materials. The shear stress-strain behavior of interface and matrix material is modeled as elastic-perfectly plastic. A local stress analysis model is used to represent the influence of interface and matrix yielding on stress distribution resulting from fiber...
