摘要

本文采用复函数法研究了双层圆形区域在反平面线性载荷作用下的动态响应。提供了各层的散射波函数，并通过叠加原理计算了各层的总波场函数。通过根据边界条件建立未知系数的无限线性方程组，进行有限项截断，得到圆孔缺陷的动态应力集中系数。此外，还通过一个具体实例讨论了有关该系数的理论和数值结果的有效性。

Analysis of dynamic anti-plane characteristics of circular laminated structures with bimaterial media

The dynamic response of a double-layered circular region under anti-plane linear loads is investigated using the complex function method. The scattering wave functions for each layer are provided, and the total wave field functions for each layer are formulated through the superposition principle. By establishing an infinite linear equation system with unknown coefficients based on the boundary conditions, finite term truncation is performed to obtain the dynamic stress concentration coefficient of the circular hole defect. Furthermore, a specific example is presented to discuss both the validity of the theory and numerical results regarding this factor.

期刊介绍： Since 1965, the international journal Acta Mechanica has been among the leading journals in the field of theoretical and applied mechanics. In addition to the classical fields such as elasticity, plasticity, vibrations, rigid body dynamics, hydrodynamics, and gasdynamics, it also gives special attention to recently developed areas such as non-Newtonian fluid dynamics, micro/nano mechanics, smart materials and structures, and issues at the interface of mechanics and materials. The journal further publishes papers in such related fields as rheology, thermodynamics, and electromagnetic interactions with fluids and solids. In addition, articles in applied mathematics dealing with significant mechanics problems are also welcome.
