The influence of the inhomogeneous initial thermal stresses caused by the heating or cooling of the inner and outer surfaces of a hollow bilayered cylinder on dispersion of torsional waves propagating in this cylinder is studied. The study is performed within the scope of the second version of the 3D linearized theory of elastic waves in initially stressed bodies, according to which the initial inhomogeneous thermal stresses are determined within the scope of the classical uncoupled linear theory of thermoelasticity. The equations related to the propagation of torsional waves are solved by a discrete-analytical method, and the numerical results found are presented and discussed.

研究了中空双层圆柱体的内，外表面受热或冷却引起的不均匀初始热应力对在该圆柱体中传播的扭转波的扩散的影响。这项研究是在初始应力体中弹性波的3D线性化线性理论的第二版范围内进行的，根据该理论，初始不均匀热应力是在经典的非耦合线性热弹性线性理论的范围内确定的。通过离散分析法求解了与扭波传播有关的方程，并给出了所得到的数值结果并进行了讨论。
