IMPROVED FORMULA FOR FATIGUE CRACK GROWTH RATEUNDER DIFFERENT STRESS RATIO

An improved formula for fatigue crack growth rate in mode I,mode III and mixed mode I-III under different stress ratio R was proposed,which was based on J-integral range ΔJ. In the formula,the test data under different R could be normalized by correction factor M,which changed the test ΔJ under diff...
