结合原子间短程作用势(Brenner势)和长程作用势(Lennard-Jones势), 利用分子动力学方法对各种锥角的碳纳米锥进行拉伸和压缩实验, 获得其载荷-应变关系曲线、受拉/压载荷极限、应变极限和构形演变等力学特性, 并与等量原子组成的碳纳米管进行比较研究. 研究结果表明, 等量碳原子组成的碳纳米锥的受拉/压载荷极限随着锥角的增大先是增大后减小, 受拉/压应变极限则随着锥角的增大而增大. 与碳纳米锥相比, 等量碳原子组成的碳纳米管的受拉/压载荷极限和应变极限显得既不突出也不逊色. 在受压构形演化方面, 与碳纳米管丰富的径向屈曲/扭转/侧向屈曲组合形变不同, 112.88°和83.62°锥角的碳纳米锥受压沿轴向完美内陷, 而60.0°和38.94°锥角的碳纳米锥受压发生侧向屈曲.
