Then, Lagrange arithmetic operator is applied in variation principle of finite deformationresilience to establish a generalized variation principle of springback.
然后应用拉氏乘子法于有限变形回弹变分原理建立有限变形广义回弹变分原理。
2
When the membrane stress is removed, circle elasticity deformation end radial shorten elasticity deformation make for resilience.
当膜力卸除后，周向弹性变形和径向缩短的弹性变形导致回弹。
3
The effect and resilience rule of the plate's plastic deformation and membrane force on the stress state and deformation state are discussed.
