Abstract
This paper presents a method of characterizing the matrix/interface-controlled strength, including scatter, of unidirectional composites under combined loading. The failure envelope is represented by a second order polynomial and the scatter is described by the strength vector whose magnitude has a Weibull distribution. The method is based on the assumption of failure originating at inherent cracks parallel to the fibers and holds promise as a means of accounting for the size effect under combined loading. In addition, the energy release rate approach is discussed as a physical model and the appropriate data are presented.
