We accompany your development from the first draft to the final design. With our expertise built up over several decades, we understand the mechanisms of the threat of in-air detonation and underwater explosion loads and have the skills to analyze and evaluate a system in a targeted manner. Regardless of whether it is a matter of individual stored systems or the entire ship. We are very familiar with the relevant building regulations on the subject of shock safety and can provide you and your customers with advice in this regard.
Shock resistance is often one of the main cost factors in the development and modernization of naval platforms (surface vessels, submarines). However, a purely experimental, non-destructive proof of shock resistance is usually difficult or even impossible. With our DYSMAS shock simulations, we close this gap and thus make a decisive contribution to the design, optimization and qualification of a platform.
Our in-house development DYSMAS (Dynamic System-Mechanics Advanced Simulations) is a highly accurate, fully coupled program system for the simulation of fluid-structure interaction (FSI) and was specially developed for the calculation of the response behavior of highly dynamically stressed systems. It can be used to model complex physical high-speed phenomena. These include underwater explosions (UNDEX), detonations near the water surface (FLOATEX), in-air detonations (AIREX) as well as deformations at high strain rates, material fracture and penetration of structures.
By combining these individual effects, DYSMAS enables us to cover the full range of threats and their effects on naval platforms and other land and air systems. This includes conventional effect systems (e.g. mines, torpedoes, missiles) as well as asymmetric threats (e.g. IEDs).
Starting in the 1980s, DYSMAS was continuously validated in numerous laboratory experiments through to comprehensive UNDEX tests on decommissioned naval vessels. Since 1996, its further development has been driven forward in German-American cooperation. DYSMAS thus represents the standard tool for all shock-related problems for the fleets of both nations.
We make our DYSMAS simulation services available to government organizations and industrial companies in all NATO member states and other countries*.
