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 si...
