Accurate prediction of springback after coining operation

Journal of Physics: Conference Series, 2018
A common approach used to reduce springback in flanging operations is to apply additional coining around the bent regions. In this strategy, the sheet metal part is compressed between two rigid dies having a clearance less than the sheet thickness. The aim is to bring additional compressive stresses especially around bending dominated regions.

Radial Basis Functional Model of Multi-Point Dieless Forming Process for Springback Reduction and Compensation

Metals, 2017
Springback in multi-point dieless forming (MDF) is a common problem because of the small deformation and blank holder free boundary condition. Numerical simulations are widely used in sheet metal forming to predict the springback.

Finite element simulation of twist forming process to study twist springback pattern

MATEC Web of Conferences, 2017
Springback is one of the most common defects found in the metal forming of automotive parts. There are three conditions which can be considered as springback i.e. flange angle change, sidewall curl and twist springback and among them, twist springback is

Finite Element Simulation for Springback Prediction Compensation

International Journal on Advanced Science, Engineering and Information Technology, 2011
An accurate modelling of the sheet metal deformations including the springback prediction is one of the key factors in the efficient utilisation of  Finite Element Method (FEM) process simulation in industrial application. Assuming that springback can be predicted accurately, there still remains the problem of how to use such results to appear at a ...
