- 論文の詳細を見る
Using very thin steel plate specimens, the effect of the plate thickness on the fatigue crack propagation was studied and the following results were obtained. In very fine grained specimens, the crack propagation rate becomes slow with an increase of plate thickness. Based on the fatigue crack propagation resistance in the plane stress (in case of extremely thin plate specimen) and plane strain (in case of relatively thick specimen) conditions and the crack tip plastic zone sizes under maximum stress and cyclic stress conditions, the effect of plate thickness on fatigue crack propagation was estimated. The experimental results coincide with this estimation.
