基于分数阶LS模型的多场耦合波的反射和透射
Reflection and transmission of multi-physics coupled waves based on LS model of fractional order
摘要
Abstract
Lorentz force is introduced by Maxwell electromagnetism theory to reflect the influence of external magnetic field on elastic wave propagation,the generalized thermo-elasticity LS model of fractional order is applied to reflect the influence of thermo-mechanical coupling effect on elastic wave propagation.The influence of external magnetic field and thermo-mechanical coupling effect on the wave mode and dispersion characteristics is analyzed by the dispersion equation.The energy flux ratios of various reflected waves and transmitted waves to incident waves are calculated by using the continuous boundary conditions,and the reliability of the numerical calculation results is verified by the normal energy conservation.关键词
