Experimental Assessment of Friction Coefficient in Deep Drawing and Its Verification by Numerical Simulation
نویسندگان
چکیده
The friction coefficient in the simulation of stamping processes should be defined. Modern software allows its definition as constant or dependence on pressure temperature. It is also useful to define different values regions, it often reflects nature deformation process. This article deals with regression and analytical models commonly used determine coefficients specified areas Analytical were verified by an experimental strip drawing test under same contact conditions. Steel sheets for automotive industry experiments simulations—extra deep quality DC 05 austenitic stainless steel AISI 304. Friction evaluated when cup was performed. A model blankholding force applied results. Conformity measured tests confirmed. reached from experiment FEM software.

Numerical and Experimental Research of Deep Drawing Process
There are mainly two methods of deep drawing analysis; experimental and analytical/numerical. Experimental analysis can be useful in analyzing the process to determine the process parameters that produce a defect free product, and the analytical/numerical modeling can be used to model and analyze the process through all stages of deformation. This approach is less time consuming and more econom...

Experimental and Numerical Investigation of Warm Deep Drawing Process of AA5052 Aluminum Alloy
Aluminum alloys have a high strength-to-weight ratio and proper anti-corrosion properties that are used in the automotive, shipbuilding and aerospace industries. The major problem with forming aluminum sheets is the low formability of aluminum sheets at room temperature. Therefore, in the present study, warm deep drawing (WDD) of AA5052-O aluminum alloy sheets with a thickness of 1mm was invest...

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Numerical and Experimental Investigation of Deep Drawing Process in Square Section of Single-Layer and Two-Layer Sheet
Deep drawing of two-layer sheet is a suitable way to achieve product with a desired shape and desired properties in sheet metal forming technology. Control of deep drawing parameter such as thinning is the most important challenge in this process. The most difficult part of this challenge is differences in material properties and geometry of each layer. In this paper, numerical approach has bee...
