The occurrence of a chain reaction from blast on atmospheric storage tanks in oil and chemical facilities is hard to predict. The current French practice for SEVESO facilities ignores projectiles and assumes a critical peak overpressure value ob[...]

In explosion--structure interaction problems such as the dynamic response of a cylindrical shell to a blast load, an accurate prediction of both blast loading and geometrical and/or material nonlinear structural response still remains a hard cha[...]

The problem of dynamic buckling of thin cylindrical tanks subjected to an external blast caused by an accidental external gaseous detonation is studied in this paper. A study is performed on flexible cylinders at a reduced scale to quantify the [...]

Numerical simulations of reinforced concrete structures subjected to high velocity impacts and explosions remain a difficult task today. For 10 years and more now, the CEA-Gramat has maintained a continuous research effort with the help of diffe[...]

This paper deals with empirical formulae predicting the perforation of reinforced concrete barriers. These formulae are usually validated for hard impacts only. Consequently, on the one hand, a simple method is proposed in case of soft impacts. [...]

The efficiency of the discrete element method for studying the fracture of heterogeneous media has been demonstrated, but it is limited by the size of the computational model. A coupling between the discrete element and the finite element method[...]

The benefit of using the discrete element method (DEM) for simulations of fracture in heterogeneous media has been widely highlighted. However, modelling large structure leads to prohibitive computations times. We propose to use graphics process[...]
