Micromechanics-Based Analysis of Fiber-Reinforced Laminated Composites

A procedure for three-dimensional nonlinear material modelling of fiber-reinforced laminated composites is presented. The material modelling procedure has a two-level hierarchical structure. At the bottom level, constitutive information about the fiber and the matrix phases are synthesized using a micromechanical model to yield the effective stress-strain response of a unidirectional lamina. At the top level, a three-dimensional lamination scheme is employed which assembles the laminae within a sublaminate, and delivers the effective stress-strain response of the sublaminate. Local stresses and strains in a lamina or in fiber and matrix phases can be recovered from the effective values at any stage. The material modelling procedure enables the use of standard displacement-based finite elements.
