Abstract: Taking the plastic forming processes of strips and plates, which, are widely applied in modern manufacturing, as background, this paper presents a systematic introduction to the research methods and results on the elastic-plastic bending, springback and wrinkling of plates, made by the authors in recent years. The calculation of the springback of strips and shaped beams after their elastic-plastic bending has been solved completely. The so-called Plastica equations, which describe the large elastic-plastic deflection of flexible stripe, have both theoretical and practical significances. The work on the double-curvature bending and stamping of plates, especially the investigation on the role of membrane forces in the large elastic-plastic deformation of plates, is creative. In the new research field of the elastic-plastic wrinkling of plates during forming processes, energy method and other semi-analytical methods have been developed and successfully applied to solving particular problems; the results obtained are in good agreement with those of the experiment.
