過渡的熱負荷を受けるブロックの応力拡大係数について : き裂面の反対側より熱負荷を受ける場合

In one of the fields of fracture mechanics, the determination of the stress intensity factors of a crack is of great importance, when a cracked body is affected under a heating load. The results heated from the same side of the crack were reported in our previous paper. In this paper, the additional results are reported on the stress intensity factors of specimens heated abruptly at a constant temperature from the opposite side of the crack. Both caustic and photoelastic methods were employed in our experiments, and the obtained values of the stress intensity factors were compared with those obtained in our previous experiments and those reported by others in the similar experiments.
