Abstract

Abstract

A new shape on the load and elongation curve of ultra high strength structural steel in tension is measured by means of the advanced physical methods. A method of calculating true stress-true strain is found in accordance with the whole load-elongation curve. The calculation results show that during the period of deformation, whether prior to or after the maximum load, all are staged power hardening. The method of calculating hardening in dex is finally studied for discussion.
