Deformation Analysis of Solid-Liquid Coupled Structure using Explicit Finite Element Program

외연 유한요소 프로그램을 이용한 고체-액체 조합 구조물의 변형해석

In this study, deformation analysis for solid-liquid coupled structure has been performed using explicit finite element program In order to model the behavior of liquid, SPH (Smooth Particle Hydrodynamics) algorithm was adopted. Crash test and simulation for the hydro-type impact energy absorber were given as an example of industrial application. The obtained good correlation between the test results and simulation reveals that the proposed method could be used effectively for the structural analysis of solid-liquid coupled problems
