Summary

A unidirectionally reinforced composite is considered, whose components are homogeneous in elastic properties but stochastically inhomogeneous in strength parameters. The material is represented as a continuous set of structural elements composed of fiber segments, matrix, and adhesive layers. A combined theoretical and experimental approach has been used to determine the microstrength distribution parameters for rectangular specimens having thin notches, which includes an analytical calculation on the state of strain and the determination of structural element dimensions, as well as experimental determination of the failure load and statistical processing.
