in sheet metal forming processes, one-stage production of conical-cylindrical parts with high accuracy is very difficult due to wrinkling and rupturing. hydrodynamic deep drawing assisted by radial pressure is one of the most applicable procedures in sheet hydroforming process on the point of producing conical-cylindrical parts. in this paper, forming pressure path is investigated as one of the...

In sheet metal forming processes with complex strain paths, a part is subjected to large plastic deformation. This severe plastic deformation leads to high plastic strain localization zones and subsequent accumulation of those strains. Then internal and superficial micro-defects and in other words ductile damage is created. This damage causes quality problems such as fracture. Therefore, design...

Today, FE-simulation of forming process has become an integral part for assessing and evaluating forming processes. The optimization, i.e. improvement of product characteristics, has been an integral part of forming simulation based virtual product development for several years now. On the other hand, the robustness of forming processes is becoming more and more focused on recently. Therefore t...

In this paper, we propose a reliability–mechanical study combination for treating the metal forming process. This combination is based on the augmented Lagrangian method for solving the deterministic case and the response surface method. Our goal is the computation of the failure probability of the frictionless contact problem. Normally, contact problems in mechanics are particularly complex an...

electromagnetic forming is a high energy rate forming process. in this process, an electromagnetic lorentz body force is used for deformation of products. in this article, electromagnetic forming process was simulated for assembly of parts as an innovative method. in this research work, the effect of important parameters of process such as discharge energy, radius and width of rectangular groov...

The sophistication and maturity of distributed component-based services and semantic web services provide a promising environment for specification-driven service composition. Given the dynamic nature of this domain, the autonomy and adaptation of software agents represent a viable solution for the composition and enactment of cross-organizational services. Currently, there are few studies that...

Suitable simulation approaches for the preliminary investigation of the electromagnetic metal forming process are presented. For this purpose an uncoupled (loose-coupled) simulation model is compared to a more rigorous sequential-coupled approach. As shown by examples, the connection between electromagnetic field and spatiotemporal evolution of the deformation of the workpiece cannot always be ...
