Abstract
Mixed mode fatigue tests are conducted using through cracked specimen. Slant through cracked specimens are made where crack angle is 15°, 30° and 45°. It is shown that factory roof is made in all crack tips due to ΔKIII, and crack growth rate decreases by the factory roof. Fatigue crack growth is simulated using S-version FEM( Finite Element Method) using crack growth criteria. It is shown that conventional crack growth criteria are not available to predict fatigue crack growth with factory roof. In authors' previous study, modified new criterion for the prediction of crack growth rate is proposed. In this study, by using new criterion, fatigue crack growth simulation is conducted, and results are compared with those of experiments and discussed.
