Finite elements

Finite elements are small subdomains into which a complex computational model is divided using the finite element method. The behaviour of these elements is calculated numerically and then combined to form a description of the entire model.

In an FEM simulation, the behaviour of a component, material or process is calculated numerically under defined boundary conditions. In cold forming, for example, this can be used to simulate how a material behaves during several forming stages.

FEM makes it possible to analyse material flow, stresses, strains and forming forces even before actual production takes place. This allows critical areas to be identified at an early stage and the component geometry, forming sequence or tool design to be optimised in a targeted manner.

FEM is an important tool for assessing and verifying the manufacturability of complex cold-formed parts. The simulation shows how the material and component behave during the planned forming process and where critical areas may arise. The results are incorporated into the manufacturability analysis alongside further technical assessments and experience-based knowledge.

MN Kaltformteile uses finite element simulation for component and process optimisation, as well as to ensure manufacturability. Among other things, the analysis covers material flow, stresses, strains, contact conditions and residual stresses, as well as the forces occurring during forming. The insights gained can be incorporated into the design of the forming sequence and the tool design.
