Available limit load solutions for plates containing embedded cracks in R6 and BS7910, a newly published global solution by Lv et al. and a new local solution recommended in this paper are validated via the reference stress J scheme using 612 finite element J cases (see Part I). The results show that the Lv et al. global limit load solution, the R6 global solution and the BS7910 reference stress solution can lead to good J predictions but the predictions may be non-conservative. A factor less than 1 should be applied to these limit load solutions to obtain conservative J predictions. The R6 local solutions may be non-conservative for bending stress dominated cases. The new local limit load solution developed in this paper is conservative for cases with weak bending stress and needs to apply a factor 0.7 for bending stress dominated cases. Recommendations for possible R6 update are provided.

R6 和 BS7910 中包含嵌入裂纹的板的可用极限载荷解决方案，这是 Lv 等人新发布的全局解决方案。本文中推荐的新局部解决方案通过参考应力J方案使用 612 个有限元J情况进行验证（参见第 I 部分）。结果表明，Lv 等人。全局极限载荷解、R6 全局解和 BS7910 参考应力解可以产生良好的J预测，但这些预测可能是非保守的。应将小于 1 的系数应用于这些极限载荷解决方案以获得保守的J预测。R6 局部解对于弯曲应力主导的情况可能是非保守的。本文中开发的新局部极限载荷解决方案对于弱弯曲应力的情况是保守的，对于弯曲应力占主导地位的情况，需要应用系数 0.7。提供了可能的 R6 更新建议。
