The numerical component design (FEM method)

The finite element method (FEM) enables a numerical component design prior to the construction of a component. All material areas of the component to be considered are broken down into infinitesimally small pieces and assigned to these material properties, depending on whether it is metal, ceramic, plastic or soldering materials.

Alumina Systems GmbH has its own ANSYS workstation, which can be used to simulate the complete soldered assembly including the solder. The soldering process itself is simulated as a stress (=”composite stresses”) and – if necessary – external stresses such as temperature changes or mechanical loads are applied. The task is to replace an existing bushing with a 99.6%Ni cap instead of a NiFe42 cap. The 99.6% nickel has an approximately 30% higher modulus of elasticity.
