摘要: A microscopic region of a unidirectional composite is modelled by finite element micromechanical analysis using generalized plane strain formulation, but including longitudinal shear loading. The capable treating elastic, transversely isotropic fibre materials, as well isotropic, elastoplastic matrix materials. Matrix material properties are considered to be temperature- and/or moisture-dependent. loading capability permits the response composites in direction. In conjunction with laminated plate point stress analysis, present has been used predict stress/strain into inelastic range graphite/epoxy [±45]4s laminate. Available experimental data for various environmental conditions indicate excellent agreement analytical predictions.
