Dimpling process in cold roll metal forming by finite element modelling and experimental validation
The dimpling process is a novel cold-roll forming process that involves dimpling of a rolled flat strip prior to the roll forming operation. This is a process undertaken to enhance the material properties and subsequent products' structural performance while maintaining a minimum strip thickness. In order to understand the complex and interrelated nonlinear changes in contact, geometry and mate...
متن کاملDetermination of Buckling Limit of Strain in Cold Roll Forming through Finite Element Analysis
In this study, Buckling Limit of Strain (B.L.S.) is introduced as one of the most important limiting factors in cold roll forming process. B.L.S. is calculated by the finite element procedure. Then for two particular processes with existing analysis and experimental results, B.L.S. has been determined and evaluated. LUSAS 12.3 is used for finite element analysis. The results show that when buck...

متن کاملAn assessment of finite element software for application to the roll-forming process
The roll forming industry has many difficulties in product development and process set-up. The design and development of rolls and processes re mainly based on trial-and-error and past experiences. Recent industrial trends demand products having high quality and tight tolerances. This equires more precise and cost-effective roll-forming processes than the ones employed in the traditional produc...
متن کاملOptimization of the strain distribution in the roll forming process using the desirability function and finite element methods
Defects of the roll forming process are affected by amount and situation of the strains distribution. The effect of the process parameters on the strain distribution in the round cross section roll forming process has been studied. Finite element and response surface method have been used for process modelling. Then desirability functions approach and overlaid counter plots have been employed f...
