Vestibular afferent responses to microrotational stimuli

Brain Research, 1991
Intracellular microelectrode recording/labelling techniques were used to investigate vestibular afferent responses in the bullfrog, to very small amplitude (less than 0.5 degree p-p) sinusoidal rotations in the vertical plane over the frequency range of 0.063-4 Hz.

Defining relations for a viscoelastic medium with microrotation

Journal of Applied Mathematics and Mechanics, 1997
The paper deals with a model of medium with microcracks and heredity. It is shown that, for the linear approximation, the constitutive equations have the form of convolutions with respect to time with some relaxation kernels. The propagation of small perturbations in homogeneous medium is studied.

Entropy minimized MHD microrotations of Cross nanomaterials with cubic autocatalytic chemical reaction

Heat Transfer, 2021
AbstractThe Cross viscosity model is a generalized non‐Newtonian nanofluid model that has widespread engineering and industrial applications like in the synthesis of polymeric solutions, polymeric latex spheres, animal blood, biological fluids, and polyacrylamides.

Microrotation effects in material fracture and damage

Engineering Fracture Mechanics, 1991
Abstract Microrotation has an important effect at the tip of a crack where the stress gradient is large. The growth of a crack is by geometry a bifurcation of crack plane due to incompatibility of microrotation at the crack tip. By means of S( strain )-R( rotation ) decomposition theorem developed recently in mechanics of finite deformation,

Microrotation analysis applied to material cracking and toughness

International Journal of Fracture, 1992
Micro cracking in a solid material is a phenomenon of solid plane bifurcation with incompatible microrotation. Therefore analysis of a microrotation field in a strained material is important in fracture mechanics. Based on the strain-rotation (S-R) decomposition theorem newly developed in non-linear mechanics of finite deformation, a new geometric ...

Study on Microrotating Structure Using Microwire Electrical Discharge Machining

Materials and Manufacturing Processes, 2014
This paper discusses fabrication method of the rotating structure using microwire electrical discharge machining (micro-WEDM). A high-speed rotating spindle has been designed and installed to in-house developed micro-WEDM equipment with two axis to enable the processing microrotating structure. In order to realize high-precision processing, a numerical

Theory of slickenline patterns based on the velocity gradient tensor and microrotation

Tectonophysics, 1991
Abstract Brittle fault zones commonly are characterized by a multitude of lineated shear planes having a wide distribution of orientations. In our model, we assume the faulted rock comprises an aggregate of rigid blocks whose surfaces are the shear planes.

Horospherical coordinates for optimal Cosserat microrotations

Mathematical Methods in the Applied Sciences, 2018
This note proposes the use of horospherical coordinates to overcome the problems associated with multiple eigenvalues occurring in the Cosserat microrotation problem. The advantages of this coordinate system are argued.

Bridging the Gap Between Continuum Mechanical Microrotation Viscosity and Lagrangian Point-Particles

Journal of Fluids Engineering, 2013
The microrotation viscosity is an essential fluid property in micropolar fluid dynamics. By considering a dilute suspension of inertial spherical point-particles in an otherwise Newtonian fluid, an explicit analytical expression for the microrotation viscosity is derived. This non-Newtonian continuum mechanical fluid property is seen to be proportional
