Magnetization as a function of strain of a Ni48.5Mn30.8Ga20.7 single crystal during 9 MPa compressive loading test was obtained by means of vibrating coil magnetometry for different static magnetic fields up to 1.15 T. The dependency is monotonic, nonlinear and shows a small hysteresis. Maximum reversible change of magnetization is 30% for a 0.6 T field, and irreversible change of about 50% is ...

  In the current work, the seismic analysis of bent region in buried pipes is performed, and effects of soil properties and modeling methods on pipe’s response are investigated. To do this task Beam, Beam-Shell Finite Element modeling and a Continuum shell FE models of a 90 degrees elbow are employed. In the Beam model, the pipe is simulated by beam elements while combined shell-beam elements a...

Electrically-induced behaviuor was compared in the non-stretched and uniaxially stretched poly(vinylidene fluoride-trifluoroethylenechlorofluoroethylene) terpolymer a member of the relaxor polymer family that exhibits fast response speeds, a giant electrostriction, high electric energy density and a large electrocaloric effect. Although the temperature dependence of the low-field dielectric con...

We present a constitutive model capturing some of the experimentally observed features of soft biological tissues: nonlinear viscoelasticity, nonlinear elastic anisotropy, and nonlinear viscous anisotropy. For this model we derive the equation governing rectilinear shear motion in the plane of the fiber reinforcement; it is a nonlinear partial differential equation for the shear strain. Special...

Using finite element nonlinear analysis, the dynamic soil pressure on perimeter retainingwalls of structures is investigated. Nonlinear Drucker Prager failure criterion is used to model the soilbehavior in the near field. The far field soil and the middle structure are assumed to behave as linearelastic materials. The soil-wall interface behavior is modeled incorporating nonlinear interfaceelem...

Nonlinear dynamics underpin a vast array of physical phenomena ranging from interfacial motion to jamming transitions. In many cases, insight into the nonlinear behavior can be gleaned through exploration of higher order harmonics. Here, a method using band excitation scanning probe microscopy (SPM) to investigate higher order harmonics of the electromechanical response, with nanometer scale sp...

We study theoretically and experimentally the mechanisms of nonlinear and nonequilibrium dynamics in geomaterials through dynamic acoustoelasticity testing. In the proposed theoretical formulation, the classical theory of nonlinear elasticity is extended to include the effects of conditioning. This formulation is adapted to the context of dynamic acoustoelasticity testing in which a low-frequen...
