Methods for Material Charcterisation–Part II

On the Use of Elastic-Plastic Material Characteristics for Linear-Elastic Component Assessments

Pages 165-169 | Published online: 19 Jul 2013
 

Abstract

In this paper the procedure of safety assessment of components by fracture mechanics analysis as recommended in TECDOC 717 is applied to two standard specimens of ductile cast iron. It is shown that the use of a pseudo-elastic Ku-value in linear elastic safety analysis may lead to non-conservative results, when elastic-plastic material behaviour can be expected.
