Hybrid Experimental-Numerical Investigation on Plastic Deformation and Ductile Failure of Anisotropic Sheet Metals
نویسندگان
چکیده
The plastic deformation and ductile failure behaviors of anisotropic AISI 1018 low carbon steel C260 Cu-Zn brass under uniaxial tensile loading were investigated. full-filed surface U-notched sheet metal was measured by digital image correlation technique. Three-dimensional finite element modeling using the Hill model calibrated post-necking strain hardening curve performed to obtain force history till crack initiation. propagation numerically simulated employing a strain-to-failure model. results from computations as global force-displacement relation, local distribution, process are found in good agreement with experimental observations.

plastic instability in equibiaxial deformation of sheet metals
plastic instability which results in the localization and failure of sheet metals has been studied in equibiaxial stretching of commercial purity aluminium sheet. attention was focussed on two main industrial conditions of the material. these were representative of the materials that could be processed by the commercial batchannealing process (slow heating, long time) or by a continuous anneali...
متن کاملDuctile Fracture Modeling - Theory , Experimental Investigation and Numerical Verification
The fracture initiation in ductile materials is governed by the damaging process along the plastic loading path. A new damage plasticity model for ductile fracture is proposed. Experimental results show that fracture initiation in uncracked ductile solids is sensitive to the hydrostatic pressure and is dependent on the Lode angle. The damage plasticity model is established on a "cylindrical dec...
متن کاملSevere Plastic Deformation of Metals
This paper provides an introduction in the field of severe plastic deformation (SPD). First of all the main methods to produce SPD materials are discussed. In the following section, the mechanisms leading to the formation of fine grains are reviewed and the influence of changes in strain path is highlighted. During post-SPD thermal annealing, some typical microstructural changes take place. The...

Two-layer metallic sheets have wide applications in various industries due to their superlative characteristics. This paper presents analytical model to investigate the formability of two-layer sheets based on Marciniak and Kuckzinsky (M-K) method using Barlat and Lian non-quadratic yield criterion. FEM simulation is also performed to calculate the forming limits based on bifurcation theory. Fo...
متن کاملRotations of brittle particles during plastic deformation of ductile alloys
Experimental evidence is presented to show that significant rotations of brittle phase inclusions of a Fe-rich intermetallic phase occur during plastic deformation on an Al Mg Si base wrought aluminum alloy. The particle rotations are quantitatively characterized, for uniaxial tension, compression, torsion, and notch-tension test specimens strained to different strain levels. The particle rotat...
