The paper gives the results of an experimental study on three sets of AM aluminum alloy cylindrical shells under axial impact. The length of the shell is 100 mm. Three different thicknesses 1.00mm, 1.42mm. and 2.00mm. are used, and the shell is fixed on a jig and struck by a moving mass M (54gm.). The influence of different impact velocities on buckling behavior is discussed (see Pig. 2 and photograghs 1, 2). It is found that when the impact velocity is less than a certain critical value Vc1, eq. (4), the shell...

The paper gives the results of an experimental study on three sets of AM aluminum alloy cylindrical shells under axial impact. The length of the shell is 100 mm. Three different thicknesses 1.00mm, 1.42mm. and 2.00mm. are used, and the shell is fixed on a jig and struck by a moving mass M (54gm.). The influence of different impact velocities on buckling behavior is discussed (see Pig. 2 and photograghs 1, 2). It is found that when the impact velocity is less than a certain critical value Vc1, eq. (4), the shell will only exhibit uniform plastic deformation in both the axial and radial directions and does not produce sinusoidal waves. Vc1 is the critical velocity usually discussed in the literature, when this velocity is exceeded, the shell buckles. When the impact velocity exceeds another critical value Vc2. the shell will further change from the axisymmetric mode into a non-uniform type of large deformation. The shell shortens greatly and it begins to lose its load carrying capacity. We believe that this second critical velocity is also quite important in the study of dynamic plastic buckling characteristics. An approximate theoretical formula for estimating Vc2 based on strain rate reversal (violation of eq. 5) is given by eq. (7).

This paper proposes a lheoretical method to analyze the buckling and postbuckling behavior of multi-layerel fiber reinforced stiffened composite cylindrical shells under uniform axial or hydrostatic compression. The influences of shear nonlinearity of the composite material and the initial imperfection of the shell geometry are taken into account. For the compatation of the critical force, potential energy method is used. Numerical results are given for boron/epoxy composite cylindrical shells with various fiber orientation and different layer numbers. Results show that the shear noalinearity of the composite materials and the initial imperfection. of the shells are both important for the buckling and postbuckling behavior of the composite cylimdrieal shells.

本文应用能量变分方法,对加筋多层的复合材料圆柱壳,进行了非线性稳定性分析,处理了均匀轴压和横向载荷两种载荷情况。文中用卡门-佟聂耳方程考虑了柱壳失稳时的几何非线性影响,同时通过剪切模量的非线性变化考虑了复合材料的物理并线性影响。本文也分析了初始缺陷对于屈曲特性的影响。文中具体计算了硼/环氧圆柱壳失稳的数值算例。分析和计算表明,材料的剪切非线性和初始缺陷的几何非线性对圆柱壳的屈曲特性有着显著的影响。
