Detonation of high explosives is of great practical importance
for both defence and civil applications. The capability to simulate
detonation processes allows not only to increase efficiency of explosive
assembly, but also to ensure material saving. Certain charge configurations
may significantly strengthen the shattering action of condensed explosives,
and gas cumulation effects can considerably increase velocity of certain
flow elements, which can also be used for practical purposes.
Detonation of three-dimensional charges
Propagation of the detonation wave over
the high explosives charge. Pressure distribution is shown.
Non-simultaneous detonations of high explosives around the airplane
Estimation of construction tolerance to explosions in the immediate vicinity of the airframe (for example, when being fired at from antiaircraft guns) is of great importance when designing battleplanes.
The time-pressure dependence has been determined in the course of a series of non-simultaneous detonations around the A-10 ground attack plane simulation by means of the GDT package.

Destruction chamber
The process of ammunition disposal in the destruction chamber has been simulated.
The chamber consists of the compartment containing the ammunition and
the outer chamber. Pressure distribution is shown.
Blast across the shelter
The problem of ensuring human safety during
terrorist acts, natural and man-caused disasters has been acquiring an
increasing urgency lately. It is especially important to be able to estimate
the degree of load on constructional elements of safety barriers and the blast
load level, effecting the human body in tasks with different geometry
configurations and distances between a man and a blast source.
