| Résumé : |
This paper deals with the development of a numerical simulation methodology for estimating damages in laminate composite plates caused by a low-speed impact. Experimental tests were performed on laminate plates reinforced with weaven carbon fibers and epoxy resin. Three thickness plates were evaluated. The impact loads were transversal and punctual. Two lamina failure criteria were evaluated. The first is the maximum stress. The second is a proposed modification of the Hashin failure criterion. Four lamina degradation criteria were evaluated too. The numerical damaged areas and lengths were similar or greater than the experimental results. |
