Abstract

It is not easy to analyze the behavior of a structural body composed of particles such as rocks using the finite element method facilitating typical element meshes because we cannot ignore the interactions among particles. In the study, we investigated the applicability of smooth particle hydrodynamics (SPH) element method for collision analysis of rock-berm by comparison with the conventional Lagrange method. As the result, SPH technique is expected to be capable of realistic simulation under collision analysis of material composed of particles.

암석과 같은 입자들로 구성된 구조체의 거동을 일반적인 요소망을 이용한 유한요소해석으로 구현하기 어렵다. 이는 입자로 구성된 구조체의 거동 해석시 입자간의 상호작용을 무시할 수 없기 때문이다. 본 연구에서는 입자로 구성된 구조체(rock-berm)의 분할에 Smooth Particle Hydrodynamics (SPH) 기법을 이용하여 충돌해석을 수행하고 이를 기존의 Lagrange 기법을 사용한 해석결과와 비교하여 SPH 기법의 적용 가능성을 알아보았다. 결과적으로 SPH 기법이 입자로 구성된 구조체의 충돌해석에 사실적인 모사가 가능한 것으로 파악되었다.
