Abstract
The invention relates to a device and a process for the measurement of mechanical material parameters, for observing and evaluating crack systems in a component, preferentially the bending of a stretched component (1) which is placed in the X direction and loaded opposite to the Y direction by at least one force producer (3), characterized by the fact that - a component (1) is irradiated by a source (4), - at least one receiver (5) is arranged on an axis (8) (Z direction) level with the component (1) at a distance to the component (1), - at least one force measuring device (7) is arranged in the force flow, and - an evaluating unit (6) which is connected to the force measuring unit (7) and the receiver (5). The invention succeeds in producing a contactless deformation measurement of a component (preferentially a bending beam) and/or the observation of the rupture zone in the event of a destructive load
