NUMERICALLY MODELING THE DEFORMATION OF AN UNDERWATER PIPELINE CONTAINING FLUID UNDER IMPACT LOADING

Abstract

A mathematical model and a method for numerically solving a two-dimensional problem of interaction between a striker and an underwater pipeline containing liquid are described. Also, some peculiarities of the wave processes for a pipeline submerged in liquid and a pipe having no environment are presented.

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