Deformation processes during disc bend loading

Abstract

A miniaturised disc bend test technique has been used to measure yield and ultimate load values for high purity aluminium, oxygen free high conductivity copper, and normalised and tempered 2·25Cr–1Mo steel. For each material details of load displacement behaviour were recorded with the test variables disc thickness, punch diameter, and die clearance. Data analysis permitted relationships to be established correlating disc behaviour with results from standard tensile tests. These correlations are discussed in terms of testing variables and the strength and ductility of the materials.
