Abstract [en]

Numerical modelling, for example FE-analysis, of powder processes requires detailed material data from physical experiments. This work intends to show possibilities to retrieve such data by TV-holography. A small disc of pressed metal powder is subjected to diametral loading. In-plane displacement field information is measured by the change in interference pattern of two laser beams diffusively reflected on the powder disc surface. Strain fields can be obtained by numerical differentiation. Findings show that non-linear elastic behaviour in the material can be detected.
