Abstract

In the present study, progressive damage analysis of open hole Carbon fiber reinforced polymer (CFRP) panel under tensile loading is being studied. Both pure UD and quasi-isotropic panel with open hole are considered as part of this work. Experimental study of open hole CFRP laminate is being carried out using 2D DIC technique. Final failure mechanisms are capture. Later, a finite element based progressive damage model (PDM) is implemented and it employs Hashin's criteria for detection of damage and material properties degradation (MPDM) method to enforce the damage. In present model, in-situ transverse and shear strengths are being used in failure criteria instead of one characterized by ASTM standard. Hence, present model can account for size effects due to ply thickness of constrained plies in multi-directional laminates. Ultimate load and damage mechanisms predicted by progressive damage analysis (PDA) are compared with experimental observations and found out to be correlating closely.
