A numerical model is presented to predict the global (or macroscopic) response of fiber-reinforced composites subjected to any stress condition. The reinforcing array is supposed to be of regular geometry, so that the model can be developed within the framework of the micromechanical theory for periodic heterogeneous media. Special attention is devoted to correctly imposing the kinematic boundary condition that have to be fulfilled by the microscopic displacement field. The reliability of the model is checked through comparisons with the numerical results of other authors.

Abstract
A numerical model is presented to predict the global (or macroscopic) response of fiber-reinforced composites subjected to any stress condition. The reinforcing array is supposed to be of regular geometry, so that the model can be developed within the framework of the micromechanical theory for periodic heterogeneous media. Special attention is devoted to correctly imposing the kinematic boundary condition that have to be fulfilled by the microscopic displacement field. The reliability of the model is checked through comparisons with the numerical results of other authors.File in questo prodotto:
