| 摘 要： | 基于各向同性金属材料在静压力作用下产生各向异性的事实，从固体中超声波的非线性理论出发，得到了在一定应力下固体的部分等效的二阶弹性常数．利用各向异性板中的SH波理论，推得了在静应力作用下与应力平行和垂直方向的SH波的频散方程，讨论了金属薄板中SH波波速与应力的关系．

| Abstract: | On the assumption that isotropic metal solid change anisotropic property in the state of stress, some equivalent second order elastic constants are calculated for metal plate with initial stress on the basis of the theory of the nonlinear acoustoelasticity. For the metal plate with initial stress, the two kinds of dispersion equation for SH wave parallel or vertical to stress direction are derived. Based on the equations, the relationship between SH wave velocity and stress of plate is discussed. |
