Efficient fe strategies for springback prediction – material modelling and computational aspects [PDF]

, 2013
Blanks of sheet metal are characterized by an intrinsic plastic anisotropic behaviour resulting from the plastic deformation during the rolling of sheets. Another type of anisotropy is elastic anisotropy which might be essential especially during elastic

Material modelling and springback analysis for multi-stage rotary draw bending of thin-walled tube using homogeneous anisotropic hardening model [PDF]

The aim of this paper is to compare several hardening models and to show their relevance for the prediction of springback and deformation of an asymmetric aluminium alloy tube in multi-stage rotary draw bending process. A three-dimensional finite-element

Grain Size Effects and Multi‐Stage Optimization in Sustainable Micro‐Deep Drawing of Copper Cups: An FEA and Experimental Study

Engineering Reports, Volume 8, Issue 1, January 2026.
Process flow. ABSTRACT The demand for miniaturized metallic components in electronics, biomedical devices, and aerospace necessitates sustainable micro‐forming solutions. Conventional deep‐drawing often suffers from stage complexity, excessive die use, and size‐effect limitations.

A novel indicator for kinematic hardening effect quantification in deep drawing simulation [PDF]

, 2019
Deep drawing simulation techniques reduce tool design costs and improve tool performance and reliability. In terms of strain hardening, mixed models capturing the kinematic effect are sometimes more accurate than isotropic models.

Springback analysis of AA5754 after hot stamping: experiments and FE modelling [PDF]

, 2016
In this paper, the springback of the aluminium alloy AA5754 under hot stamping conditions was characterised under stretch and pure bending conditions. It was found that elevated temperature stamping was beneficial for springback reduction, particularly ...

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 ...

Metamodeling of Void Closure during Hot Flat Rolling

steel research international, Volume 97, Issue 1, Page 104-115, January 2026.
This work aims to present a fast metamodel for void closure during hot flat rolling. The model takes into account every individual void of void distributions as found in industrial material and is capable of calculating the resulting void closure within only few seconds of computational time without loosing significant accuracy compared to expensive ...

Influence of boundary conditions on the prediction of springback and wrinkling in sheet metal forming [PDF]

, 2017
The high-strength steel sheets currently used in the automotive industry are prone to non-traditional behaviour during forming, being wrinkling and springback two of the most challenging geometrical predictions for numerical simulation.
