- 摘要:
- 本文以球形容器接管部位为研究对象，利用3台自制的钢质容器进行模型试验，探讨表面裂纹对不同直径、不同方式接管及接管内外表面应力场的影响程度，从理论上对测试结果进行了深入分析，并指出用中心开孔模型研究接管结构带裂纹的不足。
This artic1e takes connection section of spherical vessel as study object and uses three steel vessels manufactured by the research unit to do the model test. The impact degrees of surface cracking inside and outside of connection pipe with different diameters and connecting ways upon tress field were studied. The test results are deeply analyzed on theory and the shortcomings of using model with central hole to study the crackings on connection pipe are pointed out.1997,4(4): 9-12 收稿日期：1997-4-8参考文献：
