从蔡-吴强度理论的二次型出发，导出了正交各向异性对称材料沿远离晶粒轴的轴沿着方向的拉伸、压缩和剪切强度公式。结果进行了比较，与一些木材的剪切强度数据，他们被施加到人股骨和牛哈弗氏骨的数据。确定了与Tsai-Wu理论和现有的骨强度实验数据相一致的强度准则。
Formulas for the tensile, compressive, and shear strengths along an axis off the grain axis of a material with orthotropic symmetry are derived from the quadratic form of the Tsai-Wu strength theory. The results are compared with some shear strength data on wood and they are applied to data on human femoral bone and bovine Haversian bone. A strength criterion consistent with the Tsai-Wu theory and with the existing experimental strength data on bone is identified.
