| 8. | Thne results show that not only the nonlinear elastic critical pressure is much less than linear one , but also the inner pressure can significantly enhance the critical buckling axial load , so it provides a elastically theoretical basis for internal high - pressure forming technology 计算结果表明不仅非线性弹性临界载荷远低于线性弹性临界载荷,而且更重要的是内压很大程度上有助于提高柱壳轴向弹性临界屈曲载荷,这样为内高压成形工艺提供了弹性失稳理论依据。 |
