Component Design

The Fraunhofer-Center HTL designs components made of ceramics, metals or composites using computer simulations. Commercially available FE programs, such as ANSYS and COMSOL, are used for stress and strain calculations. The Fraunhofer-Center HTL develops low-stress structures by simulating mechanical and thermal load cases and proposes a component design for prototypes. The component design is in compliance with the guidelines of ceramic-oriented design. Design criteria for the 3D printing can also be considered, if necessary.

The simulation of the operational behavior includes exposure by static temperature or thermal shock/ thermal cycling as well as all types of mechanical loads and combinations of thermal and mechanical loads. Thereby fatigue can be observed and life cycle prognoses can be developed at the Fraunhofer-Center HTL. The required material data - if not yet known - are determined by mechanical (see Material Testing) and thermal (see ThermoOptical Measurement Devices) characterization methods. With component design, anisotropic material properties can also be taken into account - as they often occur in fiber-reinforced composites. Critical points can be detected through computer simulation, and the optimal geometry for the specific component can be identified.

When using hybrid constructions, ceramic components can be combined with metal components.  Thereby, the different degrees of thermal expansion are taken into account at high temperatures with the help of FE modeling. Using computed tomography, existing components are accurately measured, and the resulting data can be used for the FE simulation and redesign.

Components

At Fraunhofer-Center HTL, we design components from ceramics or composite materials and calculate their operational behavior. It is possible to measure the necessary data under operational conditions.
