TL;DR: In this paper, a simple approach, incorporating the normal anisotropic value R and the strain hardening exponent n, is developed to estimate springback, bendability and the maximum bending moment in pure bending.

TL;DR: In this paper, a new and practically applicable equation for estimating the LDR in the cup-drawing of a cylindrical cup with a flat-nosed punch is derived using an integral technique based on the load-maximum principle for localization of the plastic flow.

TL;DR: In this paper, a steel/polymer/steel three-layer laminate has been developed for weight reduction and vibration-damping of automobile parts and panels, and the bending process of the laminate sheets is simulated by an incremental elasto-plastic finite-element method under the plane-strain condition with care taken to describe the boundary conditions of penetration, separation and alternation of the sliding-stricking state of friction.

TL;DR: In this paper, a basic approach, incorporating material properties and geometrical parameters, is developed to estimate the amount of spring-back reduction caused by coining force upon an elementary analysis.

TL;DR: An incremental elasto-plastic finite element method based on the updated Lagrangian formulation was adopted to predict the limiting condition of collar-drawing until unloading for three punch shapes: conical, cylindrical and spherical.
