玻璃-环氧圆柱壳(管)的撞击试验表明它的破坏是渐进过程。根据一维应力波传播理论,提出了圆柱壳受轴向撞击破坏的简化模型,分析了这一破坏过程中的能量变化。结果表明本文中所提出的模型能较好地描述圆柱壳受轴向撞击吸能过程。
Impact tests on a glass-epoxy cylinder (tube) indicate that its failure is a gradual process. According to the one-dimensional theory of stress wave propagation, a simplified model of cylindrical shell damaged by axial impact is proposed, and the energy variation in this process is analyzed. The results show that the model proposed in this paper can better describe the cylindrical shell by the axial impact energy absorption process.
