Abstract
Abstract A step B test was carried out as one of the test items using large scale flat plate specimens within the Japanese PTS research project. Its experimental goal was the investigation of the crack behavior in the upper shelf region under combined mechanical and thermal loading. The experimental data were described in detail. By means of numerical simulation of the experiment, time histories of temperature distribution through the thickness, deformation and strain were obtained and compared with experimental data. Also the ductile stable crack growth by the J resistance concept was compared with experimental results. As a result, the stable crack growth of the step B test was conservatively estimated by J resistance curves obtained by 1TCT specimens. Currently, the reason of overestimation is not so clear. Triaxiality near the crack tip may be one of the reasons for the overestimation
