Stacking Sequence Effects on Performance of Composite Laminate Structure Subjected To Multi-Axial Quasi-Static Loading

In this paper, the effects of the stacking sequence on the mechanical performance and damage formation of composite laminates subjected to multi-axial quasi-static loading is investigated, considering intra-laminar damage onset. The response of the composite laminate configurations characterized by different stacking sequences subjected to multi-axial quasi-static loading have been studied to predict the influence on the static displacement and damage development. A finite element (FE) model has been used to numerically simulate the response of the composite structure. ABAQUS/EXPLICT FE environment has been considered for the analyses and Hashin's failure criteria has been adopted using a VUMAT subroutine to model the intra-laminar damage formation in the analyzed composite structure.
