Strength determination and prediction of destructive processes of composites

Abstract

This paper is devoted to issues related to strength determination and prediction of destructive processes of composites; these issues enable determining the limits of safe use of a product and to recognize when limits are reached. The model that was developed and is presented in this paper enables to describe not only the predictable strength of unidirectional composites, but also the character of the destruction, taking into account the fiber stress and/or ultimate strain distribution.
