Chapter 2.2 – Biaxial test results for strength and deformation of a range of E-glass and carbon fibre reinforced composite laminates: Failure exercise benchmark data

摘要: Publisher Summary This chapter presents a wide range of experimental data, results, and comments on the experiments, which determine accuracy current theories for predicting failure in composite laminates. It outlines source data methods used deriving material properties unidirectional laminae constituents. In some cases where laminates similar materials are tested different laboratories, same set is employed to minimize number sets issued. also compares predictions 12 with data. The covered 14 test involving 0° under biaxial direct shear loads. Other include (a) (90°/ ± 30°)s, (0°/ 45°/90°)s, ( 55°)s multidirectional loads (b) stress strain curves 55°)s, 45°)s, (0°/90°)s uniaxial discusses differences between symmetric laminated plate models theoretical analysis tubular specimens. Almost all results chosen use World Wide Failure Exercise (WWFE) derived from tests Testing tubes avoids problems associated free edge effects that encountered coupon other specimens triaxial stresses can be applied by subjecting combinations internal or external pressure, torsion axial load.
