Abstract

The invention is a device for dynamically load testing a sample that comprises a bearing, to which the sample can be directly or indirectly connected in a detachable manner, as well as a counter-bearing that can be effectively connected to the sample by means of at least one actuator element. The at least one actuator element introduces dynamic mechanical loads into the sample which Act along a load path that is directed between the bearing and the counter-bearing and extends through the sample. The at least one actuator element features a multifunctional solid body conversion material system that undergoes deformations due to the supply of energy, and wherein the deformations are at least one cause for the mechanical loads occurring within the sample. The device according to the invention uses at least one actuator element that may be configured in two alternative forms.
