Locally Resolved Hysteresis Measurements by using a Laser Extensometer – Procedure and Testing Device to Characterize Mechanical and Dynamical Properties of Samples and Components

This work investigates the mechanical and dynamical properties of samples and components subjected to cyclic loading. To this end, a procedure and a corresponding testing device is developed which enables locally resolved hysteresis measurements. The development relies on the application of a laser extensometer which has only been used to characterize the local deformation behavior under quasi-static testing conditions.

The newly developed approach is applied to carry out local hysteresis analysis on cellular elastomer components and linear PVC-foams. The measurements verify possible applications, e.g. to determine visco-elastic material properties or to characterize local fatigue behavior.
