PROPERTY DEGRADATION ANISOTROPIC COMPOSITE LAMINATES WITH MATRIX CRACKING .2. DETERMINATION OF RESOLVED STIFFNESS AND NUMERICAL STUDY OF STIFFNESS DEGRADATION

摘要

The study on properly degradation of damaged composite laminates is extended to anisotropic laminates with matrix cracking. Ln Part 2 of the paper, a solution for partitioned stiffnesses is given to complete the constitutive relations developed in Part 1. The stiffness degradation in (theta(m)/90(n))(s) cracked laminates are calculated and the results are discussed. [References: 3]
