The Kingery-Bulmash Blast Parameter Calculator calculates the blast-wave parameters of a hemispherical free field air-blast, based on the empirical relations developed by Kingery and …
Blast Pressure - an overview | ScienceDirect Topics
Blast pressure is more properly called overpressure because it is relative to ambient conditions. Shock waves are high-pressure blast waves that travel through the air at a velocity faster than …
Prediction curves or graphs are given for external blast wave properties, and internal blast and gas transient pressures. Practical techniques for explosion containment and venting are …
The blast wave generated by an explosion consists of a shock front in which the pressure rises virtually instantaneously, followed by an expansion wave in which the pressure returns to its …
The Application of Pressure-Impulse Curves in a Blast Exceedance ...
By combining the risk-based methodology of the exceedance analysis with pressure and impulse data in the form of pressure-impulse (P-I) curves, a better measure of building damage can be …
