| 摘 要： | 研究脉冲热能沉积薄板中,由于板厚方向的温度梯度和空间径向温度Gauss分布状态,所产生的辐射热能引起的弯曲运动效应。文章从非耦合的经典的Bernoulli—Euler理论出发,得到热弯曲动力学方程,求解初值问题,利用Laplace变换和Hankel变换,针对短脉冲和连续热辐射进行了分析,并给出热弹性弯曲波的数值计算结果。与文献8]的实验结果比较,二者是相符的。

| Abstract: | The bending effect of a thermal energy deposit zone in a plate irradiated by a pulsed Gaussian heat radiation on the propagation of thermoelastic waves due to the spatial temperature gradient is investigated. The dynamic equation for thermal bending is induced from the classical Barnoulli -Euler theory. Using Laplace and Hankel transformations the displacements of plate are calculated for both cases of short rectangular pulse and continuous wave. The results agree with the experimental data in ref. 8. |
