• On Non-holonomic Boundary Conditions within the Nonlinear Cosserat Continuum

  Publikacja

  • V. Eremeev

  - Rok 2019

  Within the framework of the nonlinear micropolar elastic continuum we discuss non-holonomic kinematic boundary conditions. By non-holonomic boundary conditions we mean linear relations between virtual displacements and virtual rotations given on the boundary. Such boundary conditions can be used for modelling of complex material interactions in the vicinity of the boundaries and interfaces.

  - COMPOSITES PART B-ENGINEERING - Rok 2018

  The paper is a continuation of [1] where the formulation of the elastic constitutive law for functionally graded materials (FGM) on the grounds of nonlinear 6-parameter shell theory with the 6th parameter (the drilling degree of freedom) was presented. Here the formulation is extended to the elasto-plastic range. The material law is based on Cosserat plasticity and employs the well-known Tamura-Tomota-Ozawa (TTO) [2] mixture...

• Elastoplastic law of Cosserat type in shell theory with drilling rotation

  Publikacja

  - MATHEMATICS AND MECHANICS OF SOLIDS - Rok 2015

  Within the framework of six-parameter non-linear shell theory, with strain measures of the Cosserat type, we develop small-strain J2-type elastoplastic constitutive relations. The relations are obtained from the Cosserat plane stress relations assumed in each shell layer, by through-the-thickness integration employing the first-order shear theory. The formulation allows for unlimited translations and rotations. The constitutive...

  - ZAMM-Zeitschrift fur Angewandte Mathematik und Mechanik - Rok 2011

  Przeprowadzono studium doboru mikropolarnych współczynników konstytutywnych w pewnym modelu płyty Cosseratów. Wyznaczono ograniczenia na ich wartości i przeprowadzono parametryczną analizę wpływu tych współczynników na geometrycznie nieliniowe deformacje powłok z ortogonalnymi przecięciami płatów.

• An isogeometric finite element formulation for frictionless contact of Cosserat rods with unconstrained directors

  Publikacja

  • M. Choi
  • S. Klinkel
  • R. Sauer

  - COMPUTATIONAL MECHANICS - Rok 2022

  This paper presents an isogeometric finite element formulation for nonlinear beams with impenetrability constraints, based on the kinematics of Cosserat rods with unconstrained directors. The beam cross-sectional deformation is represented by director vectors of an arbitrary order. For the frictionless lateral beam-to-beam contact, a surface-to-surface contact algorithm combined with an active set strategy and a penalty method...

• On FEM analysis of Cosserat-type stiffened shells. Static and stability linear analysis

  Publikacja

  • S. Burzyński

  - CONTINUUM MECHANICS AND THERMODYNAMICS - Rok 2021

  The present research investigates the theory and numerical analysis of shells stiffened with beams in the framework based on the geometrically exact theories of shells and beams. Shell’s and beam’s kinematics are described by the Cosserat surface and the Cosserat rod respectively, which are consistent including deformation and strain measures. A FEM approximation of the virtual work principle leads to the conforming shell and beam...
