Progressive damage analysis of unidirectional pseudo-ductile hybrid composite laminates under tension loading

In the recent researches, precise use of thin ply carbon laminates caused to create pseudo-ductile behavior in hybrid composite laminates. The majority of new studies in this field are focused on experimental verification of new pseudo ductile hybrid composites. In this paper, an accurate numerical tool are designed to predict the unidirectional pseudo ductile hybrid composites under tension loading. The thin ply Carbon layer fragmentation and further interlaminar delamination are the main failure modes of the unidirectional hybrid under tension loading. The cohesive zone modeling approach is used to demonstrate these behavior of unidirectional hybrid composites. User material subroutine (UMAT) were developed in a commercial finite element software for progressive damage analysis of pseudo ductile hybrid composites. The obtained numerical results of unidirectional pseudo ductile hybrid composites are in good agreement with the experimental results
