Three Point and Four Point Bending Test

Bend tests deform the test material at the midpoint causing a concave surface or a bend to form without the occurrence of fracture and are typically performed to determine the ductility, bend strength, fracture strength and resistance to fracture of that material.

Generally, there are two types of bending tests: 3-point bend and 4-point bend.

TK50-500 Bending Test Fixture is mostly used to determine the bend strength of woods, ceramics, and the parts with up to 50cm length.

Features of the bending fixture

  • Simple and accurate adjusting the distance between two supports by using the ruler and the marks

  • Replaceable supporting pins with several radiuses

  • Capacity: 20kN

TK50-500 Bending Test Fixture is one of the accessories of below Universal Tensile testers

The fixture has two moving supports that each one has a V-shape groove for different supporting pins.

Default diameter of supporting pins is 20mm and it can be possible to order other sizes.

A ruler is mounted on the base plate which can be used to measure the distance between two supports. The base plate of the fixture is mounted directly on the universal testing machine clamps and there is no need to open them.

The force is applied by a loading pin located above and center of the base plate. Default diameter of the loading pin is 20mm and it can be possible to order other sizes.

3point bending test is performed to determine ductility, bend strength, fracture strength and resistance to fracture of the materials. The major benefit of the test is fast and easy sample preparation and a simple test procedure. However, there are disadvantages, the results of the test are sensitive to the sample shape, loading procedure, and rate.
