Energy Finite Element Analysis of N-shaped Plate Structures with Three Types of Wave

摘要：

　　Three types of wave,i.e.bending,longitudinal and shear waves being simultaneously taken into account,the transmission and reflection coefficients at the junction are derived,and then the variations of the coefficients with respect to incident angles are discussed.For analyzing the coupling relationship at the junction,coupling elements are introduced to build the coupling matrix.Based on a special procedure to deal with the global matrix assembly,the energy flow finite element analysis of n-shaped plate is performed to solve the energy density.The numerical examples exhibit the energy density distributions and visualize the energy flux.
