【摘要】 本文利用三维光弹冻结切片法,对K_I沿容器斜接管(?)分别为15°、30°模型内拐角裂纹前缘的分布进行测定,同时利用实验所得的结果和(?)等于45°模型角裂纹自然扩展的情况,对某些疲劳扩展现象进行了定性解释.更多还原

【Abstract】 Distribution of KI along inner corner front in vessel-oblique nozzle models, skewed angle is 15° and 30° respectively is determined by 3D photoelestic-fro-zen-slide method in this paper. Some fatique extension phenomena are explained by use of the results obtained in experiments and the natural extension of corner cracks in =15° model .更多还原
