本文详细介绍了在第二次全球失效演习(WWFE-II)中用于基准三轴失效准则的输入数据。它包括(A)五个单向层板及其组成的三维弹性常数、极限应变和强度以及非线性应力-应变曲线；(B)描述了五个复合材料层板的12个挑战试验案例、铺层、层厚、堆叠顺序和加载条件。3D失效理论的发起人被要求在测试用例的盲目预测中使用这里提供的准确数据。向贡献者发布的说明也在本文的末尾提供。
This article gives details of the input data provided for use in the Second World-Wide Failure Exercise (WWFE-II) for benchmarking triaxial failure criteria. It includes (a) three-dimensional elastic constants, ultimate strains and strengths and the nonlinear stress-strain curves for five unidirectional laminae and their constituents and (b) a description of 12 challenging test cases of 5 composite laminates, the lay-ups, layer thicknesses, stacking sequences and the loading conditions. The originators of 3D failure theories were requested to use the exact data provided here in their blind predictions of the test cases. The instructions issued to the contributors are also presented at the end of this article.
