A material model for warm forming of aluminium sheet [PDF]
A material model has been developed to simulate the warm forming of Al–Mg\ud sheet. Both the hardening behaviour, including temperature and strain rate effects, and the\ud biaxial stress–strain response of the sheet are considered.

Hyperbolic hardening model for quasibrittle materials
Abstract In this study an elastoplastic hardening model for quasibrittle materials is presented. The yield surface exhibits hyperbolic meridians while its shape on the deviatoric plane is described by an elliptic function. The proposed hardening mechanism is controlled by the slope of the asymptotes of the hyperbolic meridians and thus by the ...

Continuum modelling of work hardening in precipitation hardened alloys
This thesis deals with prediction of macroscopic work hardening in a precipitation hardened alloy. The focus is on the particle contribution. A hierarchical modelling approach is adopted where work hardening in a representative material volume on the microscale is homogenized and used to represent the macroscopic hardening. The modelling on the smaller

Calibration of the hardening soil model in excalibre
The hardening soil model is one of the most commonly used constitutive models in engineering practice. This model is based on multi-surface plasticity and combines the well-known Mohr-Coulomb failure criterion, a hardening shear surface and a cap yield ...

Lattice dynamics for isochorically heated metals: A model study
The electron-excitation induced bond strength variations in metals have been predicted from density-functional theory calculations and observed experimentally, while the microscopic mechanism has yet to be elucidated.

Application of Dimension Extending Technique to Unified Hardening Model
This paper provides the process of incremental constitutive integration for the unified hardening model combined with the transformation stress method. The dimension-extending technique takes the hardening function of the hardening/softening model as the
