Bending Devices

Bending devices are mainly used to determine the elastic properties of brittle composite materials and ceramics, metals, wooden panels and rigid plastics as well as to analyze welded sheet metal.

For the selection of a bending device, various criteria have to be considered based on the test procedures and the standard specification:

Procedure: 3-point or 4-point bending test or folding test
Rigid, rotatable or tiltable bending fin and supports
Dimensions & spacing of supports and fin
Material, hardness
Maximum bending force
Accuracy of deflection
Possible risks in case of breakage

Bending test and folding test methods

3-point bending test

Simple test set-up for a variety of test methods
Especially used for elastic materials

4-point bending test

Constant bending moment between both support points (shear force-free area)
Used mainly to determine the flexural modulus of elasticity of brittle materials.
