Mechanical stress, to which design elements are generally exposed, generates stresses in the affected component or the material. If these stresses are too large, there is plastic deformation of the material in addition to the elastic, reversible deformation. The component does not return fully to its original form after the deformation, resulting in a change of shape. The beam studied in is mounted on both sides. A movable and a fixed support are included in the scope of delivery to secure the beam. The beam is loaded with a point load. The load application device can be positioned anywhere on the frame. A dial gauge records the deformation. Beams of different materials and profiles are included in the scope of delivery.
