fis-2268	Christopher, J.; Praveen, C.; Choudhary, B.K.	Comparative evaluation of two physically based models for the description of stress-relaxation behaviour of 9% chromium containing steel	2019	9	.pdf	application/pdf	4762	311	55	Loading waveform for stress relaxation tests and b) Stress-strain curve for strain hold of 1.3% at 873 K. J. Christopher et alii, Frattura ed Integrità Strutturale, 48 (2019) 554-562; DOI: 10.3221/IGF-ESIS.48.53 558 METHODOLOGY FOR PARAMETRIC OPTIMIZATION he physical constants associated with these models have been determined by the minimization of errors between experimental and predicted relaxation stress vs. hold time data for two different strain hold levels of 1.3 and 2.5% at 873 K for E911 steel. In addition to prediction of relaxation stress vs. hold time data, Model-II describes the evolution of internal stress, inter-barrier spacing and activation volume with the hold time.	cache/fis-2268.pdf	txt/fis-2268.txt
