On a ordering of area tensor elements orientations in a micropolar continuum immersed in an external plane space

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2021
The paper deals with the problems of ordering the reper orientations for a micropolar continuum immersed in an external plane space. Based on the concept of an elementary tensor volume (area) \(M\)-cells, an algorithm for comparing and matching ...

Inverse Hooke's law and complementary strain energy in coupled strain gradient elasticity

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 101, Issue 9, September 2021., 2021
Abstract The inverse Hooke's law and complementary strain energy density has been examined in the context of the theory of coupled gradient elasticity for second gradient materials. To this end, it was assumed that the potential energy density is a quadratic form of the strain and of the second gradient of displacement.

On a micropolar theory of growing solids

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020
The present paper is devoted to the problem of boundary conditions formulation in the growing micropolar solid mechanics. The static equations of the micropolar continuum in terms of relative tensors (pseudotensors) are derived due to virtual work ...

An Anisotropic Hyperelastic Constitutive Model with Bending Stiffness Interaction for Cord‐Rubber Composites: Comparison of Simulation Results with Experimental Data

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Based on the invariant theory of continuum mechanics by Spencer, the strain energy depends on deformation, fiber direction, and the gradients of the fiber direction in the deformed configuration. The resulting extended theory is very complicated and brings a nonsymmetric stress and couple stress.

Formation of the female generative structures in Deutzia scarba (Hydrangeaceae)

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2005
The development and the structure of the ovule and the embryo sac of the representative of the family Hydrangeaceae Deutzia scarba are investigated. It is established that the ovule of the given species is hemitropic, tenuinucellatic, unitegmic.

The Lagrange multipliers method in covariant formulations of micropolar continuum mechanics theories

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2018
Linear model of micropolar elastic continuum (known also as the Cosserat continuum) is considered. Kinematics and strain measures are discussed.
