Progressive Damage Analysis of Composite Laminates Under Compression

The behavior and strength of carbon ber reinforced polymer (CFRP) panels subjected\ud to tensile loading has been studied extensively by various researchers over several decades.\ud While its tensile behavior is well understood, but its compressive behavior is not. To better\ud understand the compressive behavior, it is important to develop accurate compression test\ud method. In addition, the behavior of the CFRP laminates having open cut out act as stress\ud raisers under given loading conditions. The structures are susceptible to damage near these\ud discontinuities leading to progressive failure. The progressive failure analysis (PFA) broadly\ud involves damage initiation, damage evolution and stiness degradation due to the damage.\ud It becomes very complex in case of composites due to inhomogeneity, anisotropic nature\ud and multiple failure modes
