Growth and remodelling of microcontinua
This contribution treats the theory of growth and remodelling, as presented and unified by DiCarlo. Here an attempt is made to generalize the theory for the microcontinuum. In the first part the model of microcontinuum is outlined, ...

Bone as a microcontinuum
This article introduces the modelling of bones as the linear micropolar continuum. Several numerical examples are presented, showing the influence of the microstructure on the stress distribution....

Bone modelling by microcontinuum
The article introduces basic relations describing a microcontinuum, resp. its special case - isotropic or orthotropic micropolar continuum. As an example of using this theory we present the bone tissue modelling. Numerical results conclude t...

Microcontinuum approach in biomechanical modeling
The living organs consist of tissues characterized by the hierarchical, very complex inner structure. One of theories taking this account is the microcontinuum theory elaborated by Eringen. The corresponding mathematical formulation is rathe...

Radial deformations and numerical modelling of urinary organs
In the present paper a microcontinuum model of biological tissues has been studied and has been applied to two-dimensional geometries. In case of radial deformations analytical solving and two different numerical methods have been performed....

Femur modelling based on the micropolar continuum approach
The paper deals with the femur modelling as a micropolar continuum with orthotropic material properties on macroscale and isotropic on microscale. Compact and spongy bone tissue were distinguished. Femur under single force load was studied....

Two-scales hyperelastic models
We describe a hyperelastic body at two scales: (macro) material points become (micro) deformable particles whose deformation either minimizes their elastic energies or is fixed. Application concerns the large deformations of a thick, spherical shell....

Hyperelastic models of living tissues based on the microcontinual approach
Considering material points as deformable particles either minimizing their (micro) elastic energies or holding fixed deformation, it hits qualitative and quantitative differences between mechanical behaviour of living and dead urethral wall tissue.....

On the micromorphic continua
The purpose of this paper is to give a brief summary on the micromorphic continuum theory as regarded by different authors. The attention is paid, above all, to averaging process, i.e. how the introduction of the new degrees of freedom influences the...

Elastic cylinder with microstructure
This paper is concerned with the modelling of a microstretch elastic solids. In contrast to the classical theory of continuum, the points of the microstretch material can also rotate and deform independently of their translations. The microstructure ...
