Numerics supports the following industries
The main focus of NUMERICS is Defense Technology. However, our expertise is also applied in other industrial sectors.
The development and integration of special protection for security vehicles and armoured limousines is a complex task for all car manufacturers and usually far away from their day-to-day business.
Building up on their existing FE models NUMERICS offers support to automotive industry by
- determination of blast or combined blast / fragment loads for typical and/or special protection requirements,
- evaluation and assessment of protection measures prior to the cost-intensive structural analysis,
- layout and design of protective measures to reach specific protection levels.
NUMERICS supports and consults government agencies like the criminal investigation offices in the safety assessment of security vehicles and in forensic analyses. Additionally, NUMERICS offers suitable software solutions for the customers’ in-house analyses.
The analysis of high dynamic events related to aircraft or spacecraft safety are manifold. They range from bird strike to metallic objects flushed down an aircraft toilet and from gun fire on the cockpit door to micro-meteorites impacting a satellite.
NUMERICS supports the aerospace industry by modelling and simulation of practically all impact-related problems. Thereby, the problems can either be regarded in deterministic effect simulations or be investigated in fault-tree analyses yielding failure probabilities.
Besides that, NUMERICS also supports security agencies in their evaluations and forensic investigations either by consultancy or by supplying the related analysis software (like for the investigations of the shootdown of Malaysia Airlines Flight MH17).
In chemical industry, various solid or gaseous explosive substances are stored and processed. The storage and handling of these hazardous materials require special attention. Concepts to ensure occupational safety must be drawn up in order to comply with legal requirements. Additionally, often a professional opinion is mandatory to obtain an operating permit from regulatory authorities.
NUMERICS supports the chemical industry in
- the determination of hazardous areas in case of an incident,
- the preparation of safety concepts (occupational safety, expert opinion for authorities and insurance companies),
- the determination of explosive loads (pressure-time) on building structures,
- structural design (building design, blow-out openings, materials, etc.),
- the reconstruction of explosive events.
Using our inhouse thermo-chemical code, NUMERICS is able to determine the energy release of different hazardous materials or gases. Furthermore, the numerical studies can be used to draw conclusions on possible downtimes after an incident. This information allows our customers to set up a realistic risk-impact matrix to make sound economical decisions during the construction phase as well as in negotiations with insurance companies.
Oil & Gas
In oil and gas industry, the application of explosive shaped charges during the drilling process are commonplace. As experts for shaped charge technology NUMERICS supports the drilling efforts with
- the layout and design of tailored shaped charges,
- shaped charge performance predictions.
NUMERICS also assists in risk analyses and safety concepts. The effects of explosive events or pipe rupture can be analysed applying a combination of our hydrocode and engineering tools. This enables the assessment of consequential damage, the probability of failure of affected systems and eventually of the associated risks.
Furthermore, NUMERICS has already supported companies as well as the public prosecutor’s office in the investigation of the cause of different accidents.
European building standards clearly state that dynamic “extraordinary loads” on structures cannot be processed applying the general static approaches. Hence, loading conditions arising from
- detonation events (e.g. from accidents or terrorist attacks)
- high velocity impact (e.g. tornado born missiles)
and combinations thereof have to be analysed using special simulation software like hydrocodes in order to determine the local damage due to the propagations of stress waves in the material. This requires sophisticated material models including strain-rate dependency, damage evolution and stress/stiffness degradation, which are available at NUMERICS for most of the typical building materials. If required, the actual (global) structural analysis can be performed by a structural design firm appointed by the customer or by a cooperation partner of NUMERICS.
NUMERICS also assist architects in questions of blast resistant design and other structural measures to protect vulnerable buildings like embassies, churches, public buildings or military installations.
In manufacturing industries, multi-physics simulations have long become an integral part of the design process. Thereby, dynamic problems like
- the simulation of drop or impact tests,
- the determination of accelerations or shock response spectra,
- the prediction of tool performance, etc.
require specialized software modules. In this regard, NUMERICS cooperates with Siemens and offers the software SPEED as the supplement for dynamic simulations in Simcenter 3D.
However, NUMERICS also offers manufacturers to conduct these dynamic simulations as an external service integrated in the company’s design processes.
