采用分子动力学方法，模拟了（10，10）碳、氮化硼纳米管及纳米豆荚的轴向拉伸与压缩。
By using molecular dynamics(MD) method, the axial tension and compression of the (10,10) carbon, BN nanotubes and nanopeapods were simulated.
试验结果表明：轴向应力低于单轴压缩强度80%时孔道试样在内压下拉伸破裂，压力与轴向应力没有明显关系；
The experimental results show that the cracking pressure for hollow cylinder is not influenced by the axial load when it is lower than 80% of the uniaxial compression strength.
