Abstract To examine the influence of mesh density on blast loads anti-landmines (ALMs) and improvised explosive devices (IEDs) under an armored vehicle, models with different FE densities were numerically analysed. The multi-material arbitrary Lagrangian-Eulerian (MM-ALE) algorithm was used to simulate vehicle explosions. Explicit dynamic analysis performed in LS-DYNA. Blast loading simulation ...

nowadays, tunneling in urban areas is a common activity for a variety of transportations such as subways, water supply, lifelines andsewers that may require blast operations. the characteristics of stress waves of the blast are quite different from earthquake waves. the blast waves are usually of high frequency content, short duration, equality of amplitudes in horizontal and vertical direction...

Subject-specific computer models (male and female) of the human head were used to investigate the possible axonal deformation resulting from the primary phase blast-induced skull flexures. The corresponding axonal tractography was explicitly incorporated into these finite element models using a recently developed technique based on the embedded finite element method. These models were subjected...

The vulnerability of the masonry envelop under blast loading is considered critical due to the risk of loss of lives. The dynamic behaviour of masonry infill walls subjected to dynamic out-of-plane loading was experimentally investigated in this work. Using confined underwater blast wave generators (WBWG), applying the extremely high rate conversion of the explosive detonation energy into the k...
