Damage Evolution and Determination of Thermoelastic Properties of Laminates Containing Cracks

摘要: An analytical model for the prediction of thermoelastic properties composite laminates containing matrix cracks is presented. In particular, transverse with their crack surfaces parallel to fibre direction and perpendicular laminate plane are treated. Two- three-dimensional arbitrary layup configurations covered by model. The presented expressions stiffnesses, thermal expansion coefficients, strain contributions from release residual stresses local average ply strains do solely contain known property data densities. key judicious use a solution row in an infinite isotropic medium. has been verified against numerically determined coefficients cracked angle-ply cross-ply laminates. Comparisons experimental also It shown that present very good accuracy can predict at varying densities configurations.
