Different types of biaxial specimens and associated test fixtures were developed and employed in the study. Standard IITRI specimens were used to determine tensile and compressive failure strengths of G-10 composite laminates in both fill and warp directions. Biaxial tension-compression (BTC) and biaxial compression-compression (BCC) flat coupon specimens with flexible end reinforcements were designed and tested to study failure behaviors and mechanisms of composite laminates under a biaxial tension-compression and biaxial compression-compression stress states. Tubular specimens loaded in axial tension, axial compression, torsion, internal pressure, and external pressure were employed to produce desired combinations of in-plane stresses and strains. Based on the biaxial failure envelopes obtained from the tests, notched BCC specimens (BCC(n)) were tested in a biaxial compression loading condition to study failure behavior of notched laminates under a biaxial stress state. Failure mechanisms of notched and unnotched composite laminates have been studied based on the test data and failure surface examination. Made available in DSpace on 2011-05-07T13:00:02Z (GMT).
