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.
本综述论文总结了用于均匀和非均匀介质中线性和非线性弹性波传播的弹性动力学有限积分技术(EFIT)的基本原理,并给出了超声无损检测领域的各种应用实例。这些实例包括各种结构中脉冲回波、声发射和兰姆波问题的建模,以及基于三阶弹性的非线性波传播模拟。
