Effect of strain rate on cleavage fracture of mild steel in plain strain tension testing

An investigation of the influence of strain rate on the "cleavage-characteristic stress" S sub co of mild steel is presented. It is shown that, although the brittle/ductile transition temperature T sub co changed, the value of S sub co remained equal when the strain rates varied from 5.55...

Description
Summary:An investigation of the influence of strain rate on the "cleavage-characteristic stress" S sub co of mild steel is presented. It is shown that, although the brittle/ductile transition temperature T sub co changed, the value of S sub co remained equal when the strain rates varied from 5.55 x 10 exp --4 -1.1 x 10 exp 0 /s. It is believed that, for a given mild steel, S sub co is really a characteristic parameter of cleavage fracture, which is nearly independent not only of non-metallic inclusion distribution and quench-aging but also of temperature and strain rate.
