Paper Abstract

The thermal and mechanical effects of shells with inner pressure that are exposed to CW laser are investigated in this paper. In the first step, we try to apply an analytical procedure to obtain temperature response from energy conservation equation and temperature field from the heat conduction equation, then thermal damage threshold in vacuum is obtained. When it comes to mechanical effects, numerical method is applied to study laser heating thermal stresses and analytic solution is applied for stress distribution induced by inner pressure. At last, the whole picture of damage due to combined effect is given and damage threshold is evaluated.
