✦ Synopsis

A phenomenological model for porous layered materials has been developed[ The phenomenological approach for layered materials is combined with a poroelastic constitutive model[ Explicit expressions for e}ective elastic moduli\ thermal expansion coe.cients\ and poroelastic moduli are obtained[ The obtained results reduce to those of layered materials when there are no pores[ The obtained model is applied to failure analysis of thermochemically decomposing com! posites subjected to high temperature and high heating rates[ A separate analysis of carbon _ber and phenolic resin responses explains why carbon _ber shrinkage causes more delamination failure[

The second order constitutive equation for a hyperelastic material with arbitrary symmetry is derived[ In developing a second order theory\ it is necessary to be discriminating in the choice of measures of defor! mation[ Here the derivation is done in terms of the Biot strain\ which has a direct phy
