Finite element simulation, numerical optimization
INPRO relies on its long-standing experience in the fiel of material-related process simulation.
The Finite Element Simulation (FE simulation) is a universally applicable calculation method for task definitions in engineering, which can be expressed with differential equations. The principle of FE simulation is based on continuum mechanics. In vehicle construction, these methods are used not only for static analyses of structural stiffness, but also for the calculation of crash performance or for manufacturing processes, such as thermoforming.
Usually the geometry of components is so complex that deformation and stresses under load could be only calculated using these methods. By dividing the structure into very small elements, deformation in one element can be determined using very simple approaches. INPRO's know-how consists of determining appropriate formulations for contact, large elasto-plastic distortions, complex material behaviours, element presentation, etc. The task definitions, such as simulation of elasto-plastic behaviour of sheet metal in a thermoforming process, is then formulated and solved for each element in an overall system.
