Transition to chaos and escape phenomenon in two degrees of freedom oscillator with a kinematic excitation

, 2012
We study the dynamics of a two-degrees-of-freedom (two DOF) nonlinear oscillator representing a quartercar model excited by a road roughness profile. Modelling the road profile by means of a harmonic function we derive the Melnikov criterion for a system

Active Metamaterials with Tunable Shear Nonreciprocity and Nonlinear Dynamics

Advanced Science, EarlyView.
Active gear‐based mechanical metamaterials enable simultaneous control of translational and torsional stiffnesses by 30–100×, break shear reciprocity under positive versus negative loads, broadly tune resonant frequencies, and offer programmable dynamic responses.

Investigating the Benefit of MR fluids in Shock Absorbers [PDF]

, 2013
The beneficial properties of magnetorheological (MR) fluids are applied in the design and testing of a prototype suspension system. Because MR fluids become more viscous under the influence of a magnetic field, a suspension shock absorber containing MR ...

Theory and computation of electromagnetic fields and thermomechanical structure interaction for systems undergoing large deformations

, 2019
For an accurate description of electromagneto-thermomechanical systems, electromagnetic fields need to be described in a Eulerian frame, whereby the thermomechanics is solved in a Lagrangean frame.

Generality of shear thickening in suspensions [PDF]

, 2010
Suspensions are of wide interest and form the basis for many smart fluids. For most suspensions, the viscosity decreases with increasing shear rate, i.e. they shear thin. Few are reported to do the opposite, i.e.

Squeeze flow magnetorheology [PDF]

Journal of Rheology, 2011
This paper is concerned with an investigation of the rheological performance of magnetorheological fluids under squeeze flow. Preliminary results on Newtonian fluids are first compared to Stefan’s equation. Then, unidirectional monotonic compression tests are carried out in the presence of uniaxial external magnetic fields at slow compression rates ...
