The multi-load bending complement adapts to the EX 150 traction-bending test rig. It allows the introduction of new loading cases for specimens delivered as standard with the EX150 bench: several point forces, one load distributed, a combination of distributed load and point force, 4-point bending for the study of pure bending. These new load cases can also be extended to the optional instrumented specimens of the EX150 bench.
