Abstract:
The target materials of this paper are failure analysis of fiber reinforced composite laminates. Laminates are constituted of successive layers of lamina, whose layers can differ in constituents and the orientation of the fiber. In order to study the mechanical behavior of materials, it is necessary to determine the stiffness matrix. Constitutive relation are determined by classical lamination theory of first order. Then, the composite material is applied to the failure criteria, to determine whether failure occurs in a lamina. Due the lack of maximum stress criterion, there is no interaction between the stress components, for composite was applied Tsai - Hill failure criterion. In the paper the results are presented for few materials, different sequence numbers and loads.
