On the Optimum Die Shape in Rod Drawing Process Considering Work-Hardening Effect of Material
The assessment of the influence of the work-hardening of material on the optimum die profile and drawing force in rod drawing process is the main objective of the present paper. The upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the rod drawing process through curved dies. Analytical results of drawin...
متن کاملThe mediation role of quality of work life in the relationship between information cancer and learning process
New technologies have increasingly facilitated information production process and also have made it possible for many people to access to a large amount of information. This causes information cancer phenomenon in which the information destroy resources, facilities, and human labor aimlessly and destructively. This study has been considered to investigate the relationship between the phenomenon...
متن کاملOn the optimum die angle in rod drawing process considering strain-hardening effect of material
In this paper, rod drawing process of strain-hardening materials is investigated by analytical, numerical and experimental methods. The classic upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the drawing process. For a given process conditions and mechanical properties of the rod material, the power ter...
متن کاملAnalytical Modified Model of Cold Rolling Process and Investigation of the Effect of Work Roll Flattening on the Rolling Force
Cold rolling of steel is one of the most important metal forming processes so an accurate control of its parameters during the process is necessary. In this paper, the friction coefficient has been proposed as a function of cold rolling parameters such as forward slip, forward and backward tensile stresses ,strip thickness, static deformation, resistance of strip before and after rolling ,strip...

متن کاملCold work simulation of hole expansion process and its effect on crack closure
Using cold working fastener holes is a simple life enhancement procedure that strengthens metallic components by retarding crack growth around a hole. In the present paper, the residual stress field that is induced by the hole expansion process is obtained based on different material models namely elastic perfect plastic, isotropic hardening and kinematic hardening using three-dimensional finit...
