摘要：
The state of stress around crack tip under different loadings was studied, To judge what fracture mode will occur under given loading is vital important. A prerequisite of possible occurrence of mode I or mode II fracture is proposed. The study shows that only pure mode I fracture could occur under tensile, shear and mixed loading. The prediction of K-a/K-IC by maximum circumferential tensile theory should not be interpreted as K-IIC/K-IC but as tau/sigma, The predicted K-IIC/K-IC < 1 is incorrect.
