Abstract
This survey paper summarizes the basic principles of the Elastodynamic Finite Integration Technique (EFIT) for linear and nonlinear elastic wave propagation in homogeneous and heterogeneous media and presents various examples of application in the field of ultrasonic nondestructive testing. These examples involve modeling of pulse-echo, acoustic emission, and Lamb wave problems in various structures as well as nonlinear wave propagation simulations based on third-order elasticity.
