Abstract

A numerical study is presented of the influence of crack morphology on ultrasonic pulse-echo response. Crack morphology is described as a planar crack onto which a random normal direction deviation is imposed with a specified tangential correlation length. Pulse-echo responses for ensembles of random crack profiles are computed as a function of profile height, correlation length, crack length, angle of incidence, wave mode type and signal bandwidth. Mean and variance of signal peak amplitude are compiled. Limits of validity of a Kirchhoff scattering approximation are observed through comparison to boundary element method (BEM) predictions.
