Development of a Method for Modeling the Response of a Liquid filled Deformable Pipe to an Impact Load
Abstract
A comparison of methods is presented to model the effect of an impact-based pressure wave in a fluid medium on the behavior of a deformable pipe with one closed end that contains the fluid. The predicted pipe deformation and fluid pressures using Lagrangian elements, Eulerian elements, continuum particle elements, and acoustic elements are evaluated, and the benefits and limitations of the use of each element type to model this system are discussed. Based on these comparisons, a method using acoustic elements and an acoustic medium material model to represent the nonflowing fluid in this system is presented, which shows good correlation in predicted transient fluid pressure and pipe wall deformation to experimental measurements.
