Finite element methods have been an established technique for many years for simulating the behavior of mechanical systems. They are indispensable for the reliable strength analysis of complex structures. The actual FEM calculation is typically combined with an assessment method of the resulting stresses and strains, depending in particular on the intended application and choice of material.
Services
We offer FEM simulation services and strength analyses for a wide variety of customer-specific assemblies. Our focus is on steel and welded structures, though more recently we have also been working with materials such as aluminum and fiberglass-reinforced plastic.
We cover every step of the process, from model creation through simulation and stress assessment to design optimization, and we place the utmost emphasis on our customers’ needs.
Methods
Whenever possible, we use linear-elastic analyses combined with sparse modeling, such as the use of shell elements in sheet metal structures. Of course, prestressed systems, modal and buckling analyses, and nonlinear simulations are also part of our repertoire.
The FKM guideline is primarily used for stress assessment, both for base materials and for welds. This enables a design that ensures operational reliability throughout the entire service life of the component. Since our roots lie in the metal industry, we have a wealth of experience in evaluating high-temperature structures using the EN 13445. This also includes expert advice on material selection.
Bolts are rated according to VDI 2230, and for assemblies with a high proportion of steel construction components, we have specialized post-processing methods.
In the unlikely event that damage does occur, we’re happy to assist with the damage assessment and the development of a repair solution.
