Instantly calculate blast loads with our FREE tool. This blast calculator allows you to quickly predict blast loads based on charge weight, standoff distance and angle of incidence, for the most common explosive materials. Imperial. Metric. Explosive Weight. lb. Standoff Distance. ft. Angle of Incidence.
NUKEMAP is a website for visualizing the effects of nuclear detonations.
Quantity Distance Calculator. Many States use rules based upon the explosives, their quantity, and the distance from the explosive to where people are at risk. These rules are known as Quantity-Distance (Q-D) criteria, and are based on the approach derived from the Hopkinson-Cranz Scaling Law, which is further amended by a range of coefficients.
Calculate Fragment Velocity. The initial velocity of warhead fragments can be estimated using the Gurney equation. A general form of the Gurney equation which can be used for different geometries is given in the Gurney equations in this section. It may be used to analytically predict expected fragment initial velocities.
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 Bulmash. It provides data for incident pressure, reflected pressure, incident impulse, reflected impulse, duration of positive pressure phase, time of arrival of ...
