Abstract

Explosion is considered a sudden load on structure that may result in destructive and unrecoverable consequences. In this article we will study the role of soil in vicinity of concrete tank to lower the influence of explosion. In this study, LSDYNA (one of the strong modelling programs) has been used for modelling the explosion. The results show that when the mass of explosive matter increases to 3750 KG, the pressure on the soil is about 19.5 times the highest pressure on the tank and which illustrates the role of soil on lowering the influence of pressure.

Keywords

Explosion, Tank, Soil, LS-DYNA.

Abstract

In this paper, flow pattern around an unsubmerged T-shaped spur dike in a 45 degree position, and located in a 90 degree bend with different Froude Numbers has been studied using Flow-3D and has been compared with experimental results. To determine the effect of Froude Number on flow pattern, flow pattern in longitudinal, cross, and plan sections have been studied.

Keywords
