Impetus DEFENSE package
Tailored for defense applications
This is a product for defense customers, such as military vehicle manufacturers, ammunition and weapons producers, providers of blast protection and fortification, as well as defense agencies.
Abstract
Impetus DEFENSE expands the popular Impetus BASIC package with a computationally efficient discrete particle module. The discrete particles are used to represent the physics of high explosives, air, soil, and their interaction. There is a two-way coupling between the discrete particles and the structural response, represented by finite elements.
The module makes it possible to perform very realistic simulations of complete vehicles and/or armor systems being subjected to blast loading from IEDs buried in soil. It can also be used for terminal ballistic purposes, such as warhead fragmentation and the interaction with targets.
A library with pre-calibrated high-explosives is included, such as C4, TNT and PETN. It also includes wet and dry soil models. These models are validated for high-velocity loading events. Document containing validation models also used for version control, is available via the support page.
The discrete particle module utilizes GPU acceleration which gives a total performance boost of up to 20X.
