Intrinsic nonlinear effects of dipole magnets in small rings

Physical Review Accelerators and Beams, 2016
We find that dynamic aperture depends significantly on the bending radii of dipole magnets when designing a small storage ring for Tsinghua Thomson scattering X-ray source (TTX) mainly because of the nonlinearity of the dipole field.

Fatigue Load Analysis of Yawed Wind Turbines Considering Geometric Nonlinearity of Blades

Energies
Fatigue damage of yawed wind turbine components can be caused by repeated long-term unsteady asymmetric inflow loads across the rotor swept area, necessitating fatigue load analysis to ensure the in-operation safety of wind turbines.

A geometric equation with critical nonlinearity on the boundary [PDF]

Pacific Journal of Mathematics, 2005
A theorem of Escobar asserts that, on a positive three dimensional smooth compact Riemannian manifold with boundary which is not conformally equivalent to the standard three dimensional ball, a necessary and sufficient condition for a $C^2$ function $H$ to be the mean curvature of some conformal flat metric is that $H$ is positive somewhere.

Multimode Analysis of Geometrically Nonlinear Transverse Free and Forced Vibrations of Tapered Beams

Shock and Vibration, 2022
In this study, the geometrically nonlinear free and forced vibrations of tapered beams are investigated on the basis of the Euler-Bernoulli beam theory and the von Karman geometric nonlinearity assumptions. The aim of the analysis is to determine tapered

Study Neo-Hookean and Yeoh Hyper-Elastic Models in Dielectric Elastomer-Based Micro-Beam Resonators

Latin American Journal of Solids and Structures
Micro-bridge resonator with dielectric elastomer that is sandwiched between two electrodes is studied here with geometric and material nonlinearity. Geometric nonlinearity is introduced with Von-Karman strain-displacement relationship.

Nonlinear Geometric Optics for Short Pulses

Journal of Differential Equations, 2002
This paper is devoted to study pulses whose amplitudes are so large that nonlinear effects are important before diffractive effects. This scaling is called the scaling of geometric optics as opposed to diffractive geometric optics. Here for the scaling of geometric optics, an accurate asymptotic solution is constructed and the leading amplitude ...

Integrable Equations in Nonlinear Geometrical Optics [PDF]

Studies in Applied Mathematics, 2004
Geometrical optics limit of the Maxwell equations for nonlinear media with the Cole–Cole dependence of dielectric function and magnetic permeability on the frequency is considered. It is shown that for media with slow variation along one axis such a limit gives rise to the dispersionless Veselov–Novikov equation for the refractive index.
