摘要
采用3维实体单元模拟激光辐照下静止及旋转充压柱壳的应力和应变分布,分析了柱壳可能发生破坏的位置和条件.通过对计算结果的分析表明,对于激光辐照下静止及旋转充压柱壳,裂纹都有可能在光斑边缘附近产生.但由于在旋转充压柱壳上,在过光斑中心圆周上有高应力带状区域,因此旋转柱壳有可能在这一环带区域也发生破坏.在相同的激光加载条件下,静止充压柱壳更容易在局部区域开始发生破坏.
Abstract
When a laser beam irradiates a cylinder shell,the irradiated area becomes softer and the cylinder shell will be destroyed.In this paper,a 3-D solid element was adopted to simulate the stresses of internally pressured static and rotational cylinder shells irradiated by laser.It was contrastively analyzed by numerical simulation that the crack initiated from the beam spot edge at both static and rotational cylinder shells.In addition,the fracture occurred simultaneously at the whole outer cycle through the beam center of the rotational cylinder shell.It is concluded that the static cylinder shell will be destroyed more probably at the condition of the same laser power.
