Load Characteristics on the Structure under Penetrated Blasting

摘要：

The bad characteristics of penetrated blasting acts on the slab models is researched by numerical simulation using LS-DYNA( FEM), which contrasted with the results of experiment, it indicates that, computational solution and experiment are coincide preferably. Load size of penetrated blasting affecting in the surface of structure has no relation with thickness of energy-absorbing layer but distance, charges, environmental parameters etc. The peak value attenuation along the surface and spatial pressure curve of the structure center before pressure reaches the peak vale similar S curve.
