This paper deals with the photothermal interaction of an isotropic, homogenous, semiconducting, viscothermoelastic solid cylinder in the context of Lord-Shulman's of generalized thermoelasticity theory. The cylinder rotates around its axis with constant angular velocity. The bounding surface of the cylinder has been thermally shocked. The governing equations have been constructed in the Laplace transform domain and numerically calculated inversions of Laplace using the Tzou method. The numerical results for the carrier density increment, temperatures increment, strain, stress, and stress-strain energy have been represented graphically with various values mechanical relaxation time, angular velocity parameter, and lifetime parameter of a photogenerated carrier. The mechanical relaxation time and angular velocity of the rotation parameter have minimal effects on the carrier density function and temperature increment, while its effects on the strain, stress, and stress-strain energy are significant. The photogenerated carrier's lifespan parameter has essential implications on all functions studied.

本文在Lord-Shulman广义热弹性理论的背景下，研究了各向同性，均质，半导体，粘热弹性固体圆柱体的光热相互作用。圆柱体以恒定的角速度绕其轴旋转。圆柱体的边界表面已受到热冲击。在拉普拉斯变换域中构造了控制方程，并使用Tzou方法对拉普拉斯进行了数值计算反演。载流子密度增加，温度增加，应变，应力和应力-应变能的数值结果已用各种数值表示，并用光生载流子的机械弛豫时间，角速度参数和寿命参数来表示。旋转参数的机械弛豫时间和角速度对载流子密度函数和温度增量的影响很小，而对应变，应力和应力应变能的影响却很大。光生载流子的寿命参数对研究的所有功能都具有重要意义。
