Bending strength

This is a characteristic value showing the strength against bending and is also called bend strength. When only a bending moment operates on material without shear force operating, compressive force works on the bend arc axis side and tensile force works on the outside with a boundary at the neutral surface, which neither expands nor contracts even when receiving a bend operation. Bending strength shows the maximum strength at which the test piece is broken by the bend load. The JIS prescribe two types of bend stress test methods, the 3-point bend test and the 4-point bend test, according to the load method. The units are [Pa]. This value is sometimes used to show the mechanical strength of a magnet.
