Sep 23, 2017

Three-point bending test machine and four-point bending test machine difference: (1) different loading. (2) bending strength is different.

Three-point bending definition:

A test method for measuring the bending properties of materials. The strip sample is placed in the bending test fixture to form a simple beam form. The distance between the two lower support points of the support specimen is adjustable according to the length of the specimen, and there is only one loading point above the sample.

Four-point bending definition:

A test method for measuring the bending properties of materials. The strip sample is placed in the bending test fixture to form a simple beam form. The distance between the two lower support points of the support specimen is adjustable according to the length of the specimen. There are two symmetrical loading points on the top of the specimen.

Bending strength: the maximum bending force reached before bending of the specimen. According to the loading method and the shape of the specimen, the bending strength has different calculation methods. For rectangular specimens with width b and height h
