Abstract

Abstract

Set up a geometry nonlinear finite element model consistent with experiment model to calculate shock response of piping under transient load with nonlinear transient dynamic time history method and made comparison between corresponding experiment data and numeric results. By way of this comparison, the exploration study has been done for how to simulate the gap of support and how to confirm the gap stiffness.
