| 摘 要： | 采用Ｒ－Ｎ全释放解剖法测定了焊接加热处理形成的压缩歼余应力在复妆式板板厚方向的三维分布,采用分段钻孔的方法对压应力层深度进行了验证,取得了比较满意的结果。通过本文工作,提出了一种经过修正的测定高应力梯度下三维残余应力的方法。

| Abstract: | The triaxial residual stresses in clad plate weldments by Anti|Welding Heating Treatment (AWHT) were determined through Rostenthal|Norton total|relaxed section method. The depth of the compressive residual stress layer induced by AWHT was verified with the hole drilling method step by step, and rather satisfactory results were obtained. A modified triaxial residual stress determination method was prompted in the paper. |
