Abstract

The laminate analogy is very useful for the calculation of the strength of composite materials with short fibres. In connection with the maximum strain criterion, the lamination theory is suitable for predicting the strength of composites with short fibres. The prediction of the laminate strength is carried out by evaluating the stress state within each layer of the laminate based on the classical lamination theory. Finite Element Method (FEM) is used as a tool to predict the laminate strength. Numerical simulation has been prepared by using a commercially available ANSYS code.
