Abstract

This paper proposes a genetic algorithms-based approach for impact load identification of composite structure, which can identify the impact location and reconstruct the impact force history simultaneously. In this study, impact load identification is formulated as an optimization problem. Combining with a forward impact response model, genetic algorithms adaptively identifies the impact location and force history by minimizing the difference between the computed analytical responses and measured ones. To improve computational efficacy, a micro-genetic algorithms is adopted to accelerate convergence. Numerical simulation study demonstrates the effectiveness and applicability of the proposed method.
