An analysis method for deep drawing process design
J.H. Vogel,D. Lee +1 more
TL;DR: In this article, an analysis method was developed that predicts the strain distribution in deep drawn sheet parts based on plane stress characteristic theory, which neglects both normal and shear stresses acting across the thickness of the material.
Journal ArticleDOI
Prediction of history-dependent forming limits by applying different hardening models
TL;DR: In this paper, the authors proposed an extension of Marciniak and Kucźynski's inhomogeneous model, except that the roles of isotropic and Prager-Ziegler kinematic hardening have been examined in detail while the flow theory of plasticity is applied.
Journal ArticleDOI
Closed die forging analysis of polycarbonate using an upper bound approach
TL;DR: In this article, a model for the closed die flashless forging of a work-hardening polymer material (polycarbonate) using an upper bound approach is developed using deform geometry, effective strains and stresses are computed at various stages in the process.
