Bifurcation of hemitropic elastic rods under axial thrust [PDF]

Quarterly of Applied Mathematics, 2013
In this work we consider the analysis of unshearable, hemitropic hyperelastic rods under end thrust alone. Roughly speaking, a nominally straight hemitropic rod is rotationally invariant about its centerline but lacks the reflection symmetries characterizing isotropic rods. Consequently a constitutive coupling between extension and twist is natural. We

Representation formulae of general solutions in the theory of hemitropic elasticity [PDF]

The Quarterly Journal of Mechanics and Applied Mathematics, 2006
We consider the steady state oscillation equations of the theory of elasticity of hemitropic materials. We derive general representation formulae for the displacement and microrotation vectors by means of six scalar metaharmonic functions. These formulae are very convenient and useful in many particular problems for domains with concrete geometry. Here

Pseudovector hyperbolic differential operators of hemitropic micropolar elasticity

Вестник Чувашского государственного педагогического университета им. И.Я. Яковлева. Серия: Механика предельного состояния, 2021
В статье обсуждаются вопросы, связанные с выводом и преобразованиями дифференциальных операторов, соответствующих модели гемитропного микрополярного континуума, при изменении ориентации базисного репера. Приводятся необходимые сведения из алгебры псевдотензоров.

Functional bases for transversely isotropic and transversely hemitropic invariants of elasticity tensors [PDF]

The Quarterly Journal of Mechanics and Applied Mathematics, 1998
Summary: We obtain a set \({\mathcal I}\) of 20 invariants for the action of O(2) on the space of elasticity tensors. It is shown that \({\mathcal I}\), together with seven additional invariants linked by seven relations, yields a functional basis for the action of SO(2), while a different set of 21 elements with 21 relations is added to \({\mathcal I}\

Reducing natural forms of hemitropic energy potentials to conventional ones

Вестник Чувашского государственного педагогического университета им. И.Я. Яковлева. Серия: Механика предельного состояния, 2023
В работе рассматривается проблема приведения естественных энергетических форм потенциалов напряжений (силовых и моментных) к конвенциональному виду. Приводятся несколько энергетических форм для гемитропной упругой среды в терминах асимметричных тензоров напряжений и деформаций.

A polynomially irreducible functional basis of hemitropic invariants of piezoelectric tensors

Communications in Optimization Theory
For piezoelectric tensors, Olive (2014) proposed a minimal integrity basis of 495 hemitropic invariants, which is also a functional basis. In this article, we construct a new functional basis of hemitropic invariants of piezoelectric tensors, using the approach of Smith and Zheng.

Plane harmonic waves in a hemitropic micropolar body

Вестник Чувашского государственного педагогического университета им. И.Я. Яковлева. Серия: Механика предельного состояния
В настоящей работе рассматривается процесс распространения плоских монохроматических связанных волн перемещений и микровращений в линейном полуизотропном микрополярном теле. Получено уравнение для определения волнового числа продольной и поперечной плоской монохроматической волны.
