Abstract
An overview is given of the state of the art of theories and procedures for predicting and analysing failure in composite materials. Of the scores of failure theories available, only those representative of each of the following categories are discussed: limit or noninteractive, interactive, and failure mode-based theories. The validity and applicability of the various theories are evaluated from the point of view of convenience of application and agreement with experimental results. Both lamina and laminate failures are discussed. In the case of ultimate laminate failure, a progressive damage scheme coupled with a failure mode-discriminating criterion is discussed. Special attention is given to textile composites where new three-dimensional experimental results are reported and a new interlaminar failure theory is proposed.
