Physical property measurements are increasingly required to support component design and process modelling using finite element analysis (FEA) and other computational methods.
At 3DForms U.K. we will help you build a solid process for these based on our considerable experience in determining these properties, using state of the art techniques, for metallic and non-metallic materials.
In order to model processes or components operating at elevated temperatures, it is often necessary to determine the following properties as functions of temperature:
- Thermal diffusivity
- Heat capacity
When combined with the room temperature density, these properties can be used to calculate the thermal conductivity as a function of temperature.
The mechanical properties of materials can heavily be influenced by the material’s processing methods including how much a material is soft, strong, brittle or otherwise.
Work hardening or strain hardening for example can be used during metal processing to strengthen the material by low temperature plastic deformation. In low carbon steels, how ductile or brittle the material is can heavily on the process of work hardening. While cold working may for example help increase the steel’s tensile and yield strengths, i.e. the material is stronger and harder to deform; this comes at the expense of the materials ductility which introduces a lot of internal energy in the material as a result. This in turn may influence the environments in which such a material performs best.
