| 摘 要： | 针对强激光辐照下的圆柱薄壳，利用有限元方法，计及材料参数随温度变化的关系，实现了对激光辐照下柱壳表面瞬态温度场的数值模拟，以此为基础，模拟并分析了一定加载条件下应力波在壳体中的传播规律，以及造成的结构振动响应的过程和特点。

| Abstract: | The thermal-mechanical effects of cylindrical shell that are illuminated by intense lasers are studied.The transient temperature field and structural response of shell are numerically simulated by the finite element method.The stress wave transmitting of shells under the given applied load is analyzed,and the characteristics of structural vibration obtained also.The physical properties of the material as function of temperature are accounted for in this computation. |
