- Title
A FATIGUE LIFE ESTIMATION OF SPECIMENS EXCESSIVELY PRESTRAINED IN TENSION.

- Abstract
Fatigue tests were carried out on a shipbuilding-grade rolled steel, prestrained to various degrees up to 85% of its static tensile fracture strain. It is observed that prestraining degrades the fatigue life in the domain of low-cycle fatigue, but this effect is not apparent in the medium-to-high cycle fatigue regime. A set of equations has been developed to assess the behaviour of tensile prestrained materials for the entire range from low-to-high cycle fatigue. The data acquired in this study validate the authenticity of these formulae sufficiently well.
