# Constitutive Relation and Stiffness Degradation of Cracked Anisotropic Composite Laminates(Ⅱ)——Determination of Resolved Stiffness and Investigation of Stiffness Degradation for Cracked Laminates

• The study on property degradation of damaged composite laminates is extended to anisotropic laminates with matrix cracking. In(Ⅱ) of the paper, a solution for partitioned stiffness is given to complete the constitutive relations developed in(Ⅰ). The stiffness degradation in(θm/90n)s cracked laminates is calculated and the results are discussed.
