摘要
针对由于轴压引起的壳体弹塑性屈曲而导致的材料在成型和制造过程中的失效力学行为 ,选择适用于轴压的屈曲模态函数 ,利用能量法确定了屈曲参数满足的一般非线性方程组 。
Nonlinear equations are established for failures in materials during forming and manufacturing, which result from elastoplastic buckling under axial compression, using energy methods and the buckling function. And equilibrium curves are described in detail for elastoplastic critical failures in perfect or imperfect, geometric linear or nonlinear elastoplastic materials.
