Abstract

A procedure has been developed for simulating progressive damage in composite laminates using a combination of an accurate stress analysis technique, a quasicontinuum approximation of the damaged material, and artificial neural networks. A response surface model, based on a multi-layer feed-forward network, is constructed as a surrogate for the computationally intensive higher fidelity finite element models by performing a series of numerical experiments and then observing the responses from those experiments. Two partially recurrent neural network topologies are proposed as part of an adaptive structural health monitoring strategy that emphasizes damage diagnostics as a prelude to predicting potential damage. A finite element model for nonlinear analysis of composite plates coupled with a micromechanics-based mechanistic model for modeling the initiation and evolution of damage and for predicting the effective composite properties is used to construct data for the response surface models.
