Mechanical behavior of mild steel up to rupture: characterization and validation
نویسندگان
چکیده
In this work, the initial anisotropy and its evolution with strain, hardening and rupture of DC04 mild steel are characterized by using (i) a phenomenological constitutive model composed by the non-quadratic Yld2004-18p yield criterion combined with an isotropic hardening law and (ii) a macroscopic rupture criterion. For this purpose, an inverse methodology of material parameters identification is implemented and a numerical prediction of rupture is performed. The obtained results are validated in a cup deep-drawing benchmark.

Controlling the Mechanical Properties and Corrosion Resistance of Mild Steel by Intercritical Annealing and Subcritical Tempering
The effects of intercritical annealing and subcritical tempering on the mechanical properties and corrosion resistance of mild steel were studied. It was revealed that intercritical annealing followed by quenching resulted in the development of a ferritic-martensitic dual phase (DP) microstructure with high tensile strength, disappearance of the yield-point phenomenon, superior work-hardening b...
متن کاملA Predictive Model Accounting for the Mechanical Behavior of Galvanized Alloy Layers on the Mild Steel
Zinc coating is formed by the heterogeneous assembly of the Γ, Γ1, δ, ζ and η phases whose mechanical properties greatly differ from each other. Thermal strains resulting from large differences between thermal expansion coefficients are partially relaxed by the formation of a crack network. In order to model this phenomenon, initial hardness, thermal expansion coefficient αi and toughness (KIC)...

This article describes a numerical study on the TOX-clinching process of the steel sheets. In addition, the influence of plastic anisotropy of the material on joining parameters is analyzed by evolution of the joint parameters such as undercut and neck thickness and punch force-displacement curve. Finite element analysis with ABAQUS/CAE-Explicit program is used to simulate two dimensional and t...
