Direction-reversing traveling waves

The symmetries of a physical system provide a key to much of its dynamical behavior. As a consequence equivariant bifurcation theory has met with remarkable success in a wide range of physical applications, including fluid dynamics, laser physics, and chemical oscillations. (See, for example, refs. [1,2].) In this note we consider physical systems depending on a parameter/~ that are translation...

Cyclic Reversing K-symmetry Groups

We consider discrete invertible dynamical systems L with the property that the kth iterate L k possesses (reversing) symmetries that are not possessed by L. A map U is called a (reversing) k-symmetry of L if k is the smallest positive integer for which U is a (reversing) symmetry of L k. In this paper we discuss the particular case that L possesses a cyclic reversing k-symmetry group. We derive...

Irreversibility transition of colloidal polycrystals under cyclic deformation

Cyclically loaded disordered particle systems, such as granular packings and amorphous media, display a non-equilibrium phase transition towards irreversibility. Here, we investigate numerically the cyclic deformation of a colloidal polycrystal with impurities and reveal a transition to irreversible behavior driven by the displacement of dislocations. At the phase transition we observe enhanced...

medium dense non-cemented carbonate sand under reversed cyclic loading

carbonate materials are mostly found in tropical areas, where exploiting gas and oil resources are of high concern. their unique behavior under shear loading first was recognised during oil resources investigations in the persian gulf. off-shore structures have been placed on carbonate soils which are highly crushable.during storms cyclic loading imposes on the bases of structures lied down on ...

Effect of viscoelastic deformation of soft tissue on stresses in the structures under complete denture.

The time dependency of stress distribution in the supporting structures under dentures was simulated, under three loading conditions, by visco-elastic finite element stress analysis. In this simulation, viscoelastic material, was used as a model for soft tissue. The results indicate that the viscous flow of soft tissue and the loading position are factors determining stress intensity in the sup...
