Numerical Simulation of Buried Structure Response to Strong Dynamic Load

Abstract:

Three kinds of numerical methods (Lagrange, ALE, SPH-FEM) were used to analyze the response of an fully buried underground structure under blast loading, the differences of these three methods and factors which affect calculation accuracy were analyzed and compared. The results show that the Lagrange method can give more accurate results, but it should be taken into account that the shape of the ammunition may influence the calculation of impact stress in soil.
