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 for complex geometries, including curvatures, joints, etc. The goal of the present contribution is to demonstrate the capability of two different simulation techniques to investigate wave propagation mechanisms in pipelines, i.e. the curvilinear elas their applications are discussed for both straight and curved pipelines.
