Stress-strain measures used in the ANSYS package to solve elastoplastic problems at finite strains
N. V. Ovchinnikova Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
It is shown that the Dienes (or the Green–McInnis–Naghdi) stress rate is used as an objective stress rate of the Cauchy stress for solving elastic-plastic problems in the ANSYS program instead of the Jaumann stress rate announced in the ANSYS Theory Reference. The strain tensor is not the logarithmic or Hencky strain measure as is announced in the ANSYS Theory Reference, but it is a right nonholonomic strain tensor such that the left tensor is generated by the Dienes derivative.
Key words:
elastoplastic body, finite strain, strain measures, stress measures, ANSYS program.
