Abstract

The problem of heating a non-homogeneous thermoelastic layer induced by absorbing a penetrating laser radiation throughout its volume is solved by employing the dual-phase-lag theory of thermoelasticity. The surfaces of the layer are taken insulated and traction free. Using the Laplace integral transform technique, a solution to the considered problem is obtained. The results presented graphically for the distributions of the upper surface temperature, temperature, displacement, and normal stress.

激光辐射体积吸收作用下的广义功能梯度热弹性层

摘要

通过采用热弹性的双相滞后理论解决了通过在其整个体积中吸收穿透性激光辐射来加热非均匀热弹性层的问题。该层的表面采用绝缘和无牵引力。使用拉普拉斯积分变换技术，获得了所考虑问题的解决方案。结果以图形方式显示了上表面温度、温度、位移和法向应力的分布。
