Elastic disk with isoperimetric Cosserat coating
نویسندگان
چکیده
A circular elastic disk is coated with an beam, absorbing shear and normal forces without deformation linearly reacting to a bending moment change in curvature. The inextensibility of the beam introduces isoperimetric constraint, so that length initial circumference constrained remain fixed during loading disk/coating system. mechanical model for this system formulated, solved general loading, particularized case two equal opposite traction distributions, each applied on small boundary segment (thus modeling indentation fiber). stress fields, obtained via complex potentials, are shown evidence nice correspondence photoelastic experiments, ad hoc designed performed. presented results useful design fibers at micro nano scales.

Granular hypoplasticity with Cosserat effects
This paper provides an extension to Cosserat mechanics of a recently proposed version of hypoplasticity [1], and this extension is achieved economically by means of a novel complex-variable formulation of Cosserat theory. The present work represents a compact synthesis and theoretical framework for both non-polar and polar hypoplasticity, and it encompasses various special cases considered in t...
متن کاملWave chaos in the elastic disk.
The relation between the elastic wave equation for plane, isotropic bodies and an underlying classical ray dynamics is investigated. We study, in particular, the eigenfrequencies of an elastic disk with free boundaries and their connection to periodic rays inside the circular domain. Even though the problem is separable, wave mixing between the shear and pressure component of the wave field at ...
متن کاملFinite Element Analysis of Stress Concentration around a Blunt Crack in a Cosserat Elastic Solid
The problem of a blunt edge notch of elliptic contour in a strip of Cosserat (micropolar) elastic material under tension has been analyzed via two-dimensional (plane stress) finite element analysis. Both 3-node constant strain triangular elements and 4-node isoparametric elements were used. Three cases were explored: Cosserat characteristic length much less than the crack root radius, equal to ...
متن کاملObservation of Cosserat elastic effects in a tetragonal negative Poisson’s ratio lattice
Size effects are explored experimentally in a tetragonal lattice structure. Size dependence of rigidity is nonclassical elastic and is interpreted via Cosserat elasticity. The characteristic lengths are about a third the cell size. The Cosserat characteristic length for torsion is `t = 5.6 mm. The characteristic length for bending is `b = 5.4 mm. The size effect in torsion was a factor 4.5 in r...
