Development of a Reliability-Mechanical: Numerical Model of Mechanical Behavior of a Multilayer Composite Plate

Due to the design of uncertainty caused by manufacturing processes and measures, that may affect composite structures, mechanical reliability analysis of a multilayer composite plate, using the finite element method, been the subject of this paper. To that end, we propose a reliability-mechanical numerical model, conditioned by Tsai-Wu failure criterion. This model was developed in two steps, first, the development of a deterministic model, afterwards, a probabilistic computation. To get to our lens, a probabilistic study was carried out to highlight the influence of design parameters on random damage to composite structures, using the Monte Carlo simulation method, which made it possible to estimate the failure P-f probability of the studied structure. The results obtained show that the uncertainties loading and winding angle are the first two responsible for the composite structure failure.
