Experimental study on the dynamic responses of foam sandwich panels with different facesheets and core gradients subjected to blast impulse

International Journal of Impact Engineering, 2020
Sandwich panels with an energy-absorbing core material have exhibited great potential in lightweight structures for blast protection. In this study, the deformation/failure modes of sandwich panels against blast impulse were investigated experimentally ...

Blast Injuries

The Journal of Emergency Medicine, 2015
Blast injuries in the United States and worldwide are not uncommon. Partially due to the increasing frequency of both domestic and international terrorist bombing attacks, it is prudent for all emergency physicians to be knowledgeable about blasts and the spectrum of associated injuries.Our aim was to describe blast physiology, types of blast injuries ...

On Aerodynamics of Blasts

1953
Publisher Summary This chapter begins with explaining the influence of a structure on the form and pressure field of a passing blast by a simplified model whose results show that the reflected shock is very weak and a slipstream exists in a physical sense and the bend forms an almost vertical wall(the slope).

Blasting Safety for Surface Blasting

2016
One of the largest single problems that face a blasting contractor is blasting safety. The principal disturbances created by blasting are flyrock, ground vibration and air blast which may cause damage to structure nearby and the source of serious conflict with the inhabitants who live close to the operation.
