Progressive Damage Analysis of Open Hole Carbon Fiber Reinforced Polymer Panel under Tensile Loading.
Masters thesis, Indian Institute of Technology Hyderabad.
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.
