Abstract
AbstractThis paper presents a novel approach for reconstructing the characteristics of non-punctual impact events on elastic plates by introducing multi-parameter optimization. The objective function is minimized using two heuristic optimization techniques, particle swarm optimization, and differential evolution, to reconstruct impact force characteristics. The force was regarded as taking the form of a uniform pressure over a part of the plate called the patch. The Maxwell-Betti theorem was considered to decouple the problem of localization and the time history of the applying unknown load. The approach based on heuristic optimization methods has been proven a performance to locate the impact zone. A comparison between particle swarm optimization and differential evolution was discussed.
