Wave propagation in plate structures for crack detection

This paper presents the method of analysis of the wave propagation process in cracked plates. For modelling the plate new type of finite spectral plate element with a crack was elaborated. It was assumed that the crack having an arbitrary length, depth and location was parallel to one side of the plate. Elastic behaviour of the plate at the crack location was considered as a line spring with a varying stiffness along the crack length.
