MULTI-AXIAL STRESS LOAD TEST DEVICE, MULTI-AXIAL STRESS LOAD TEST METHOD, AND METHOD FOR PREDICTING STRESS CORROSION CRACKING

摘要

PROBLEM TO BE SOLVED: To provide a multi-axial stress load test device capable of observing a surface of a test piece.;SOLUTION: A multi-axial stress load test device 100 includes: a fixing jig 30 which fixes a peripheral edge part 13 of a test piece 10 formed like a flat plate so that a front surface 11 in an inner part 14 on the inner side of the peripheral edge part 13 of the test piece 10 is exposed; and a pressing jig 20 having a convex portion 24 which presses a rear surface 12 of the inner part 14 of the test piece 10 toward the front surface 11 side. The inner part of the test piece 10 is bent in accordance with a shape of the convex portion 24 by the fixing jig 30 and the pressing jig 20, whereby a multi-axial stress field is generated in the test piece 10.;COPYRIGHT: (C)2014,JPO&INPIT
