Effects of finite curvature on soliton dynamics in a chain of nonlinear oscillators
Abstract. We consider a curved chain of nonlinear oscillators and show that the interplay of curvature and nonlinearity leads to a number of qualitative effects. In particular, the energy of nonlinear localized excitations centered on the bending decreases when curvature increases, i.e. bending manifests itself as a trap for excitations. Moreover, the potential of this trap is double-well, thus...

For a curved chain of nonlinear oscillators it is shown that the interplay of curvature and nonlinearity may lead to symmetry breaking when an asymmetric stationary state becomes energetically more favorable than a symmetric stationary state. This phenomenon is studied analytically for a minimal model which effectively takes into account both mechanisms of localization: linear and nonlinear one...
متن کاملnon-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
