NUMERICAL MODELING OF THE PIPELINE WITH LIQUID DEFORMATION UNDER THE IMPACT LOADING

Abstract

The mathematical model and the numerical analysis procedure of a plane dynamic interaction problem for a striker and a pipeline with and without liquid are described. Some particular features of wave processes are shown for a free of support section of a pipeline and for a pipeline supported on a fixed flat surface. The influence of a filling up liquid is analyzed.

Keywords: pipeline, elasticity, plasticity, deformation, impact, liquid.
