Abstract: Using the method derived in Part I, plane-strain sheet-forming processes are analyzed and discussed. Stretch and deep draw forming by cylindrical and flat-bottom punches are presented and compared ...

Abstract: A formulation for finite element simulation of highly nonlinear problems including friction and contact with arbitrarily shaped rigid surfaces is proposed (CFS approach), prompted by difficulties ...

Abstract: A simplified numerical procedure to predict springback in a 2D draw bend test was developed based on the hybrid method which superposes bending effects onto membrane solutions. In particular, ...

Abstract: Unpredicted sheet forming failures of dual-phase (DP) steels can occur in regions of high curvature and with little apparent necking. Such failures are often referred to as “shear fractures”. ...

Abstract: Friction-stir welding (FSW) promises joints with low porosity, fine microstructures, minimum phase transformation, and low oxidation compared with conventional welding techniques. It is capable of ...

Abstract: Commercial methods for the mechanical design of part and die shapes often rely on trial-and-error methods applied to either experiments or simulation, as guided by intuition. Academic alternatives ...
