Title: Study of Axes Rotation during Simple Shear Tests on Aluminum Sheets

Abstract

In order to model accurately the anisotropic material behavior during finite element simulations, a precise description of the material yield locus is required. Beside the shape (linked to the material model used), the size (related to the isotropic hardening) and the position (kinematic hardening) of the yield locus, its orientation is of particular interest when large rotations of the material are encountered during the simulations. This paper proposes three distinct methods for the determination of the material yield locus rotation: a method based on the Constant Symmetric Local Velocity Gradient (CSLVG), a corotational method and a method based on the Mandel spin. These methods are compared during simple shear tests of an aluminum sheet.

  • Simple shear tests are performed on low carbon steel pre-deformed in conventional, asymmetric and orthogonal-asymmetric rolling. The simple-shear tests were carried out at 0 deg. , 45 deg. and 135 deg. with respect to the previous rolling direction. For a reduction ratio of 15%, a transient stagnation in the hardening rate is observed at reloading for all changes in strain path. The shear stress level, the hardening rate and extent of the plateau appear to be insensitive to the preliminary applied rolling conditions. After a reduction ratio of 50%, plastic instability was detected at reloading for all the changes ofmore » strain path and rolling conditions studied. A specific heat treatment was then designed allowing the material to become ductile after rolling while retaining the fine microstructure and therefore the high strength. Promising results were obtained essentially for 45 deg. shear tests.« less

  • The stellar kinematics of nearby, optically luminous, elliptical galaxies of moderate radio power is investigated to determine whether these galaxies are kinematically unusual or show evidence for a relationship between their radio properties and stellar dynamics. A model describing the structure and kinematics of elliptical galaxies is developed which allows for oblate, prolate, and triaxial figure types. The model is fitted to the data to estimate the position angle of the rotation axis and the scale and amplitude of the rotation curve for each galaxy. The results demonstrate that elliptical galaxies possess a wide range of rotation velocities and thatmore » the projected minor and rotation axes can be oriented very differently. There is a tendency for the rotation axis to align with one of the symmetry axes of the projected figure. 37 references.« less
  • A method has been developed at the All-Union Scientific Research Technology Institute for Compressor Machinery Building for fastening tubes in a tube sheet by axial press fitting, which lacks the disadvantages of fastening tubes to tube sheets by expansion and welding. Comparative tests of joint quality of expansion and press fitting methods are made and the results indicate that the tightness and strength of joints made by the two methods are equivalent. All joint samples were tested for tightness by the mass spectrometric method. Taking into consideration the high quality of the axial press fitting joint, and the high effectivenessmore » of the tool, it is desireable to fasten tubes in tube sheets by the axial press fitting method.« less
  • Nonequilibrium molecular dynamics simulations have been performed in order to compare the characteristics of planar Couette, planar elongation, uniaxial stretching, and biaxial stretching flows in simple fluids at different strain rates. After deriving the periodic boundary conditions for general flow fields and introducing some methodological improvements for elongation flow calculations we simulated the combination of shear and shear-free flows as well. We found that even at high strain rates where simple fluids exhibit strong non-Newtonian behavior (shear-thinning) it is a reasonable approximation to consider the two planar flows to be rotationally equivalent. This is because in planar Couette flow themore » in-plane normal stress difference of simple fluids is approximately zero even far from equilibrium. Similarly to planar Couette flow, the trace of the pressure tensor and the internal energy vary approximately as function of the 3/2 power of the strain rate in shear free flows. However, the individual diagonal elements of elongation flow pressure tensors deviate considerably from this approximation. In the extension direction the pressure seems to have a minimum in terms of the strain rate in every shear-free flow. We have discussed the implications of these results. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.« less
