摘要

围绕平板试样和管道结构的裂尖拘束度以及失效评定图（Failure Assessment Diagram，FAD）进行研究，旨在探明试样和管道之间的适配性和关联性。基于有限元法获得了中心裂纹板（Central Cracked Plate，CCP）试样以及含裂纹承压管道裂尖的拘束度，发现单轴加载作用下的CCP试样裂尖拘束度与轴向拉载荷作用下的厚壁管道较匹配，而双轴载荷作用下的CCP试样与内压作用下的薄壁管道较匹配。此外，获得了CCP试样和管道结构的FAD，发现CCP试样的FAD受厚度的影响较小；指出平行于裂纹方向的应力是使得结构的失效评定曲线（Failure Assessment Curve，FAC）提高的主要因素。最后，发现具有相同拘束度水平、裂尖复合程度以及加载方式的两种结构，CCP试样的FAC高于承压管道的FAC，即采用CCP试样的FAD评定管道结构是不安全的。

Abstract

The crack tip constraint and failure assessment diagram （FAD） in both plate specimen and pipe structure were the focus of analysis， with the goal of studying compatibility and correlation of between the two.Based on the finite element method，constraints at crack tip of central cracked plate （CCP） specimen and cracked pressure pipe were obtained.It was found that crack tip constraint of CCP specimen under uniaxial loading is better matched with thick-walled pipeline under axial tensile loading，while CCP specimen under biaxial loading is better matched with thin-walled pipeline under internal pressure.In addition，the failure assessment diagram of CCP specimen and pipeline were obtained.It was found that FAD of CCP specimen is less related with thickness，when the thickness of pipe is within the range of thick wall or thin wall； was also pointed out that stress parallel to the crack direction increases the failure assessment curve （FAC） of the structure.Finally，it is found that FAC of the central crack plate specimen is higher than that of the pressure bearing pipeline，for the two structures with the same constraint level，and crack tip mixed mode degree and loading mode.That is，it is unsafe to use FAD of CCP specimen to evaluate pipeline.
