- 論文の詳細を見る
In order to investigate the threshold condition of micro fatigue crack propagation under mixed mode, tests of cyclic plane bending, cyclic torsion and their combinations are carried out with a stress ratio R=-l. Annealed cracked specimens made of carbon steel are used in the tests. Based on the assumption that a crack begins to propagate when the circumferential principal stress near its tip reaches a critical value, the threshold stress of the crack propagation under the mixed mode can be determined by making use of the test results of cyclic plane bending and cyclic torsion.
