Blast Mitigation Analysis of Semi-Buried Structure

Fluid Structure Interactions for Blast Wave Mitigation

Soil-Structure Interaction of Buried Pipes Under Cyclic Loading Conditions

The safety of lifelines, as the most important urban facilities, under different conditions highly depends on the safe design and performance of these buried structures. This cannot be achieved unless their actual behaviors are well understood and considered at the designing stage. A new physical model was developed in Amirkabir University of Technology to study the behavior of buried pipes und...

Coupled Euler–Lagrange modeling of buried structure response to blast loading

A coupled Euler–Lagrange solution approach is used to model blast loading on a buried structure. The coupling algorithm is discussed along with a benchmark calculation.

Shock ( Blast ) Mitigation by “ Soft ” Condensed Matter

It is a common point that “soft” condensed matter (like granular materials or foams) can reduce damage caused by impact or explosion. It is attributed to their ability to absorb significant energy. This is certainly the case for quasistatic type of deformation at low velocity of impact widely used for packing of fragile devices. At the same time a mitigation of blast phenomena must take into ac...

Experimental Studies of Mitigation Materials for Blast Induced Tbi

The objective of this experimental study is to compare the effects of various materials obstructing the flow of a blast wave and the ability of the given material to reduce the damage caused by the blast. Several methods of energy transfer in blast wave flows are known or expected including: material interfaces with impedance mismatches, density changes in a given material, internal shearing, a...

Modeling and Simulation of Interactions between Blast Waves and Structures for Blast Wave Mitigation

Explosions occur in military conflicts as well as in various industrial applications. Air blast waves generated by large explosions move outward with high velocity, pressure and temperature. The blast waves not only incapacitate military and civilian personnel, but also damages buildings, vehicles, and other properties. Hence, there has been extensive research on how to mitigate blast wave effe...
