正交异性体弹性动力学方程另一形式自相似解

Deduction of self-similar solutions of other form on elastodynamics equations for an orthotropic anisotropic body

为进一步简化正交异性体的弹性动力学方程,在对正交异性体弹性动力学方程的自相似解深入研究基础上,采用复变函数论的方法,导出了另一形式自相似解的表达式.该解在解决裂纹扩展问题中具有重要的应用价值.

In order to predigest the elastodynamics equations for orthotropic anisotropic body, by using the theory of complex analytic, a representation of self-similar solutions of other form is deduced based on the further study of the equations. This solution has an important applied value in solving crack propagation problems.
