Failure of Composites with Short Fibers

open access: yesCommunications, 2010
Strength-based failure criteria are commonly used with the finite element method (FEM) to predict failure events in composite structures. The laminate analogy is very useful for the calculation of the strength of composite materials with short fibers ...
