摘要

我们采用离散-连续方法来研究质量-质量超材料链中的几何非线性弯曲波。我们以耦合微分差分方程和连续极限偏微分方程的形式推导了非线性运动方程。研究了以孤应变波形式存在连续方程分析解的可能性。

Modeling of Nonlinear Bending Strainwaves in a Metamaterial Chain

We use a discrete–continuum approach to study geometrically nonlinear bending waves in a massin-mass metamaterial chain. The nonlinear equations of motion are derived, both in the form of coupled differential–difference equations and in the form of partial differential equations in the continuum limit. The possible existence of an analytical solution of continuum equations in the form of a solitary strain wave is examined.
