Blast simulation of explosives buried in saturated sand

Identification of Interaction Pressure Between Structure and Explosive with Inverse Approach

“…Another situation where structure-explosive interaction must be considered is the response of structures to buried explosions [18][19][20][21]. In such circumstances, the interaction between the structure and the explosive products (e.g.…”

“…ejected sand/soil and fragments) that serve as impact loading carriers must be considered. Fortunately, recent advances in computational power and the development of modern hydro-codes have made such simulations feasible, even when modeling strong structure-explosive interactions [3,[19][20][21][22][23]. Although, such studies are still in an early stage of development, often with numerical issues such as mesh dependence [22] and without considerations of effects such as sand/soil self-reaction and air-sand/soil coupling, such efforts are still the method of choice for determining the interaction tractions and the corresponding dynamic structural response.…”

Using Geographic Information System for Simulation and Decision Making in Blasting

“…Zhao & Zhang have used DDA numerical simulation and demolition for a brick chimney by directional blasting [7]. Furthermore, material point method (MPM), Object-oriented technology and neural network have been used for blasting simulation [8][9][10][11][12][13].…”
