Response of plates subjected to air-blast and buried explosions
… The response of a structure subjected to a blast load is influenced by many factors, namely stand off distance, mass of explosive, degrees of confinement and medium surrounding the charge. This study focuses on characterizing the transient deformation of test plates which have been exposed …

Review of Methods for Calculating Pressure Profiles of Explosive Air Blast and its Sample Application
Blast profiles and two primary methods of determining them were reviewed for use in the creation of a computer program for calculating blast pressures which serves as a design tool to aid engineers or analysts in the study of structures subjected to explosive air blast. These methods were …

Design of a composite combat helmet liner for prevention of blast-induced traumatic brain injury
Air blast-induced traumatic brain injuries (TBIs) represent a significant percentage of military personnel injuries observed in Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). Prevalence of blast-induced TBIs is attributed to several factors, including improved body armor, …

Numerical Simulation of a Liquid Jet Atomization and Break-Up Using ANSYS-CFX 12.0
… of a pressure jet atomizer and an air-blast atomizer is shown. By employing a Lagrangian particle tracking method to track the path of the liquid particles, the liquid jet/spray phenomena was studied in light of low and high back pressure environments. The 'BLOB' primary atomization …

A Mineralocorticoid-Dependent Effect of Prestress on Avoidance Responding in Rats
… occurred in normal rats whether foot shock, air blast, or simple handling served as the prestress. The effect did not, however, occur in adrenalectomized rats. The effect also did not occur in intact rats who were maintained on 1.5% NaCl drinking fluid, a procedure which is known to inhibit …

The response of concave singly curved fibre reinforced moulded sandwich and laminated composite panels to blast loading
… into composite failure processes resulting from air-blast. Most of the research has been focused on flat panels, whereas there is relatively little on curved structures. This dissertation reports on the effect of air-blast loading on concave, singly curved fibre reinforced sandwich and composite …

Analysis of blast mitigation strategies exploiting fluid-structure interaction
Blast attacks have become the most pervasive threat in both civil and military contexts. However, there is currently a limited understanding of the mechanisms of loading, damage and failure of structures, and injury to humans produced by blast. This thesis seeks to advance our current understanding …
