plot load–extension diagrams

Description:

• 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 SE 110.48is 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.
• The transition from elastic to plastic deformation is observed and determined in the experiment.
• The values obtained are used to create a load–extension diagram, in which the nonlinear behaviour of the deformation is demonstrated.
• The parts of the experiment are laid out clearly and housed securely in a storage system.
• The entire experimental setup is constructed in the SE 112 mounting frame.
