Abstract

In this paper a cycle J integral formula for CT-Specimen was improved as follows： J=2/Bb(1U+2P )+2Ue/Bb{一1.2025a/W+0.6233 0.3a/W0.53 一0.02Sin[/0.23(a/W一0.53)] 0.53＜a/W0.95 This formula is applicable to the crack propagation range of 0.3a/W0.95. In comparison with the same kinds of cycle J integral formula, the application range of the above expression is enlarged, and its precision is also increased to a certain degree
