The
strength of a material is a measure of where it can be expected to fail
under an applied load. For a tensile loading configuration the ultimate
tensile strength is the maximum of the engineering stress/strain curve.
The
fracture strength under constant strain rate conditions, the point at which
ductile or brittle fracture occurs, is another measure of a material's
strength. For brittle materials this may be measured in a three point bending
configuration, the fracture point for the material defines its flexural
strength. |
