Stability Analysis of Carbon/Epoxy Plate with the use of Finite Elements Method

Resumo

The Laminated plates subjected to in-plane compressive loads are studied in this research, taking into

account laminate different configurations and boundary conditions. The critical buckling load for these configura-
tions is calculated using a commercial Finite Elements Program. The mesh convergence is tested, and the 60x60

mesh is chosen because their results are very close to the classical references, and the time of execution is lower
than sixty seconds. The Finite Element Program is performed and the results obtained show a good agreement
with the literature, which demonstrate the validity of the model adopted. The critical buckling load and its mode
are evaluated, and the influence of several boundary conditions and the fiber directions are studied. The results
obtained are discussed, and the influence of the different design parameters of the laminate on static stability is
verified.
