Numerical Modelling of the explosion effect on buried transporting water, oil and gas piplines in different soils by ALE Method

In this paper, parametric studies were performed on some pipes buried in soil under blast loadings. The effects of various parameters, such as the physical properties of liquid, air, soil, pipe, and T.N.T were investigated. The Arbitrary Lagrangian-Eulerian (ALE) method was used in the LS-DYNA softw...
