Abstract

Reconstruction of impact force history from corresponding impact responses such as strain, acceleration, displacement, etc. is useful when measuring impact force acting on structures. In this study a wavelet deconvolution technique was applied to the impact force reconstruction. First, deconvolution technique using Haar wavelet was formulated. Then finite element simulation on the impact crushing of thin-walled square column was conducted. Comparisons of the reconstructed impact force to the one obtained by the finite element analysis demonstrated effectiveness of the wavelet deconvolution technique.
