Mechanical Behaviour of Conventional Materials at Experimental Conditions of Deep Drawing Technological Process

Journal of Theoretical and Applied Mechanics, 2012
The paper deals with experimental investigations on the me- chanical behaviour of body-centred-cubic (BCC) and face-centred-cubic (FCC)-conventionally structured sheet metalic-metalic materials under stress-strain conditions of a deep drawing process determined by a coeffi- cient close to the limiting one for Steel 08 and punch diameter of 50 mm.

Metamodeling of a deep drawing process using conditional Generative Adversarial Networks

, 2022
Optimization tasks as well as quality predictions for process control require fast responding process metamodels. A common strategy for sheet metal forming is building fast data driven metamodels based on results of Finite Element (FE) process ...

Lubricant-free deep drawing using CO2 and N2 as volatile media injected through laser-drilled microholes

MATEC Web of Conferences, 2018
Most metal forming processes use lubricants based on mineral oils as an intermediate medium to reduce friction and wear. To avoid the well-known drawbacks of oil lubrication, a novel and environment friendly lubrication system for deep-drawing processes ...

Improving the formability of magnesium by cushion-ram-pulsation

MATEC Web of Conferences, 2018
The application of forming processes using lightweight magnesium alloys is known to be difficult with regard to minor formability caused by a small number of active slip systems, especially at low temperatures. However, a new approach for deep drawing at

Thermomechanical Treatment of Martensitic Stainless Steels Sheets and Its Effects on Their Deep Drawability and Resulting Hardness in Press Hardening

Metals, 2020
The deep drawability of three Martensitic Stainless Steels (MSS) alloys under conventional press hardening thermomechanical process conditions was investigated. The three alloys differ in the content of the main elements C and Cr.

Scratch Modeling of Paint Coated Sheet Metal for Multi-Stage Deep Drawing Process

, 2018
The scratch phenomenon of paint coated sheet metal in multi-stage deep drawing has been investigated. The tensile tests at a quasi-static strain rate of sheet metals coated with two different types of paint were conducted along the rolling, diagonal, and
