【摘要】 通过对滑移线场分析，得出静水应力与ω，β的简单关系式．根据三维有限元计算结果，得出了裂尖处静水应力分布情况，分析了影响浅裂纹静水应力减小的原因，并验证了滑移线场分析中提出关于β和ω论点的合理性．更多还原

【Abstract】 The simple relationship betWeen ω, βand the hydrostatic stress by using theory of slip line field was gained. According to the results of three-dimension FEM computation, the distribution of hydrostatic stress at crack tip has been obtained, the reason about the influence on the decrease of hyfrostatic stress of shallow notch has been analyzed, and the reasonable viewpoint of p and ω in analysis of slip line field has been verified. A new method is provided for theory analysis of shallow crack on the elastic-plastic fractIJre.更多还原
