【摘要】 通过对一大型90°弯头进行应力测试与爆破试验,得到了内压载荷下该厚壁弯头的外壁应力分布情况,确定了弯头的薄弱部位,并将试验结果与理论计算结果进行了比较。试验结果可为大型厚壁弯头的设计,制造及使用提供参考数据。更多还原

【Abstract】 Through the stress measurement and explosion test of one large diameter 90° elbow,the stress distribution in the external wall of this elbow subjected to internal pressure was obtained,and the weak portion in the elbow was also determined.Compare the experimental data with the theoretical results.And the result of the test can be referenced in design,fabrication and application of large diameter thick elbow.更多还原
