Abstract

A force/strain relation (incorporating shear effects) for the transverse impact of beams is established in the frequency domain. Inversion by use of a fast-Fourier-transform (FFT) algorithm is shown to allow the force history to be determined. The effects of sampling rate and size are considered when analyzing experimental data.
