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

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 597-612, 10 February 2026.ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...

Springback prediction of magnesium alloy sheet with nonlinear combined hardening
工程科学学报, 2017 Springback is regarded as one of the main defects that occur in sheet-metal forming processes. Therefore, improving its prediction accuracy, especially under highly nonlinear conditions, is important for researchers. In this paper, constitutive equations

steel research international, Volume 97, Issue 2, Page 827-837, February 2026.Finite element simulations of deep drawing of commercially pure titanium sheets using single‐radius and varying‐shoulder‐radius dies are conducted. Two types of nonassociated flow rules are applied, and the results are verified by comparing them with the experimental results.

Change of the yield stress in roll formed ERW pipes considering the Bauschinger effect [PDF]
, 2017 ERW pipes formed with the roll forming process show a yield stress distribution along the circumferential direction and their quality is strongly influenced by the magnitude and by the distributions of the yield stress.
