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 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.
Learning Objectives/Experiments
Load on a beam with a point load
Plot a load–extension diagram and determine the nonlinear
behaviour
Compare the load and relief curves
Demonstrate the invalidity of the superposition principle in
the plastic region
Features
Observe and determine the transition from elastic to plastic
deformation
Plot load–extension diagrams
Specification
