| 摘 要： | 利用转轴变换公式,讨论了双材料非弹性主方向界面裂纹问题。在特征方程组的判别式Δ1′>0和Δ2′>0时,得到一种特殊情况的非弹性主方向界面裂纹应力场的理论公式,给出了双材料参数对界面裂纹应力场分布的影响规律,其结论对双材料结构改进有一定的参考价值。

| Abstract: | In this paper,the nonelastic principal direction interfacial crack of biomaterial was discussed by axis transformation formulas.In the case that the characteristic equations' discriminates meet such following conditions as and,the theoretical formula of interfacial crack stress field of a special non-elastic principal direction can be obtained and the laws of influence of biomaterial parameters on the stress field are given.The above conclusion has some referential values to the improvement of biomaterial s... |
