本文提出了一种用有限元法计算正交各向异性材料应力强度因子的简便方法。使用该程序,几个案例进行了分析,以说明各向同性和正交各向异性材料的行为之间的差异,并因此指出一些不准确的断裂韧性值为辐射松引用在目前的文献。此外,还给出了绿色辐射藻新的断裂韧度值。
A simple procedure for using the finite element method to calculate the stress intensity factor of othotropic materials is presented in this paper. Using the procedure, several cases are analysed to illustrate the difference between the behaviour of isotropic and orthotropic materials and hence point out some inaccuracies in the fracture toughness values for Pinus radiata quoted in the current literature. In addition, new fracture toughness values for green P. radiata are given.
