Abstract

A procedure has been developed for calibrating the non-linear elastic machine deformation and demonstrated for evaluating J at 653 K and 803 K for a modified 9Cr-lMo steel. The calibration procedure involves determining the non-linear elastic relation between machine deformation x m and load (P), from the Px t data for a blank specimen with known elastic compliance C (as measured at the loading pins) deforming in the elastic regime, using the relation x m (p)=x t -C.P (1)
