Bend Test

Method for measuring stiffness and yield properties of certain materials. There are no standardized terms for reporting bend test results for broad classes of materials; rather, terms associated with bend tests apply to specific forms or types of materials. For example, materials specifications sometimes require that a specimen be bent to a specified inside diameter (ASTM A-360, steel products). A bend test for ductility of welds is given in ASTM E-190. Results of tests of fiberboard are reported by a description of the failure or photographs. (ASTM D-1037)
