Determination of Material Strengths by Hydraulic Bulge Test
The hydraulic bulge test (HBT) method is proposed to determine material tensile strengths. The basic idea of HBT is similar to the small punch test (SPT), but inspired by the manufacturing process of rupture discs-high-pressure hydraulic oil is used instead of punch to cause specimen deformation. Compared with SPT method, the HBT method can avoid some of influence factors, such as punch dimensi...
متن کاملMechanical properties determination of dual-phase steels using uniaxial tensile and hydraulic bulge test
Numerical simulations of sheet metal forming processes need the establishment of highly reliable results, which in turn need the accurate identification of mechanical properties. In this paper a study is presented on the choice of the characterization function of flow stress-strain curve of sheet metal materials, as well as the selection of the best yield locus, based on experimental uniaxial t...
متن کاملMaximum Norm Wellposedness of Nonlinear Kinematic Hardening Models
We prove the wellposedness, with respect to the maximum norm, of stress-strain laws of nonlinear kinematic hardening type, in particular of the Chaboche model.
متن کاملThin Film Bulge Test of Nanocrystalline Metals
Free-standing nanocrystalline copper (Cu) films with grain size around 39 nm are fabricated by thermal evaporation and characterized by the plane-strain bulge test. Young’s modulus and yield stress at a 0.2% offset are about 110 ~ 130 GPa and 400 MPa, respectively. Results show that no grain growth is observed and the predominant plastic deformation mechanism is grain boundary sliding accompani...
متن کاملOn a simple cyclic plasticity modeling with implicit kinematic hardening restoration
This paper presents a fully three-dimensional plastic constitutive modeling framework suitable for the prediction of cyclic loading at large number of cycles. It can require only one yield surface and it is motivated by a simple rheological model where a restoration of the kinematic hardening is introduced. The classical kinematic hardening rules are then simply adapted leading to time-dependen...
