本文讨论了从实验载荷-载荷点位移曲线确定紧凑型试样J积分的方法。Merkle和Corten的原始分析，其中占紧凑型试样中的张力分量，提出了沿着的简化版本（的分析），被证明是基本上等同于原始配方。根据Landes、步行者和Clarke的实验结果，推荐了一个进一步简化的表达式作为确定紧凑试样J的最佳表达式。
Methods for determining the J integral from an experimental load versus load point displacement curve for the compact specimen are discussed. The original analysis by Merkle and Corten, which accounted for the tension component in the compact specimen, is presented along with a simplified version (of the analysis) that is shown to be essentially equivalent to the original formulation. Based on experimental results from Landes, Walker, and Clarke, a further simplified expression is recommended as the best expression to use for determining J for the compact specimen.
