Horizontally polarized shear or Lamb waves are especially useful in the ultrasonic inspection, since they can probe both the outer and inner surface of the pipelines. A simulation of their propagation is relatively easy in straight pipelines, much har**ynamic finite integration technique (CEFIT) and the local interaction simulation approach (LISA), developed by F. Schubert et al. and P. P. Delsanto et al., respectively. The two techniques are briefly reviewed in the 2nd and 3rd section and examples
