TL;DR: In this article, the authors present a comprehensive approach to simulate an explosion occurring inside a buried axisymmetric lined cavity, which considers all the stages of the process: detonation of the internal charge, the shock wave propagation in the internal gas and its following interaction with the cavity's shell lining including multiple reflections; soil-structure dynamic interaction, including multiple gap opening/closure and wave propagation.

TL;DR: In this paper, the effect of the charge size on the blast pressures has been investigated and a new insight with regard to the pressure distribution on the walls as well as the pressure attenuation depending on these parameters has been gained.

TL;DR: In this article, the sensitivity of the residual blast pressure to the heat capacity ratio and internal energy of an interior explosion was investigated. But the authors focused on the residual pressure in a room with limited venting.

TL;DR: In this article, the authors proposed a comprehensive approach to simulate the blast response of a lined cavity in a porous soil by using a coupled Godunov-variational-difference approach.

TL;DR: In this article, a comprehensive approach to simulate the effects of an explosion occurring inside a buried infrastructure tunnel on the soil surface and on nearby tunnels is presented, taking into account both bulk and shear elastic plastic behavior, including the effect of the soil pressure on the yield strength for the stress tensor deviator.
