Micromechanical Models of the Cochlea

Physics Today, 1992
Understanding human perception is at the forefront of scientific research goals today. The development of robots, virtual reality, speech coders and speech recognition devices depends on a good understanding of how we hear. The cochlea is the part of the inner ear that converts acoustic signals to the neural code that conveys auditory information to ...

Bridging Micromechanics Model

2011
The conventional approach to the mechanical properties of a material is based on a pragmatic philosophy that demands an experimental determination of material response characteristics. This approach certainly offers the best advantage for isotropic materials.

Micromechanical Modeling of Composites Fracture

Volume 1: 21st Design Automation Conference, 1995
Abstract The paper considers the new micromechanical models of fracture of fiber-reinforced composites. The main emphasis is made on the determination of the exact analytical solutions of appearing fracture problems, which allow derivation of the closed functional formulas for limit fracture stresses.

Micromechanical model for elasticity of the cell cytoskeleton

Physical Review E, 2008
Semiflexible polymer networks, such as cell cytoskeleton, differ significantly from their flexible counterparts in their deformation energy storage mechanism. As a result, the network elasticity is governed by both enthalpic and entropic variations. In addition, the enthalpic effect shows two distinct regimes of energy storage mechanism, the affine and

Lattice models in micromechanics

Applied Mechanics Reviews, 2002
This review presents the potential that lattice (or spring network) models hold for micromechanics applications. The models have their origin in the atomistic representations of matter on one hand, and in the truss-type systems in engineering on the other.

A MICROMECHANICAL INELASTIC MODEL FOR HISTORICAL MASONRY

Journal of Earthquake Engineering, 2006
A micromechanical damage model for the finite element modelling of historical masonry structures is presented in this article. Masonry is considered as a composite medium made up of a periodic assembly of blocks connected by orthogonal bed and head mortar joints.

Micromechanical modeling of the epimysium of the skeletal muscles

Journal of Biomechanics, 2008
A micromechanical model has been developed to investigate the mechanical properties of the epimysium. In the present model, the collagen fibers in the epimysium are embedded randomly in the ground substance. Two parallel wavy collagen fibers and the surrounding ground substance are used as the repeat unit (unit cell), and the epimysium is considered as

On the resolution dependence of micromechanical contact models

Wear, 2007
In this study we deal with the problem of normal contact between rough surfaces. A power spectral density of the asperity heights which obeys a power-law within a given range of wavelengths has been considered. Hence, the resolution dependence of the statistical parameters computed according to the random process theory, of the plasticity index and of ...

A Micromechanical Model of Airway-Parenchymal Interdependence

Annals of Biomedical Engineering, 2000
The forces of parenchymal interdependence in the lung are potent inhibitors of airway smooth muscle shortening, as evidenced by the marked dependence of bronchial responsiveness on lung volume. In this study we developed a mathematical-computer model of the effects of parenchymal interdependence on airway smooth muscle shortening.

Cyclic fatigue of ZTC — Micromechanical modelling

Mechanics of Materials, 1993
Abstract Crack bridging is an important mechanism in zirconia toughened ceramics (ZTC). A micromechanical model describing the toughening induced by this mechanism is first briefly recapitulated. The metastable tetragonal zirconia precipitates in the ceramic matrix transform to monoclinic phase under high stresses due to macrocracks in the matrix ...
