Abstract

Abstract

Anidea of stiffness partition is proposed to develop the constitutive relations foracracked composite laminate with anisotropic constraint layers. The governing equation of the coupled stiffness problem is derived after partition. As an example, the stiffness degradation for cracked(-θ_m/90_n/θ_m)_s laminates is studied.
