摘要：

Failure of laminated composites in compression is often ascribed to a mechanism of fiber microbuckling. Following this interpretation, a model is presented where the fiber is schematized as an elastic beam and the matrix as an elastic foundation. In comparison with previous models, however, the strain in the matrix is distributed through the thickness of a ply and lower failure stresses are obtained. An original flexion-compression device designed for investigating the elastic behavior in compression and the effect of the loading mode on the characteristics of failure is then described. Results on glass/epoxy resin unidirectional composites and laminates are discussed.
