Analysis of transient wave propagation dynamics using the enriched finite element method with interpolation cover functions
作者：
Highlights：
• A novel finite element method enriched by interpolation cover functions is developed for transient wave analysis.
• The potential linear dependence (LD) problem has been completely removed.
• Higher order interpolation can be achieved without adding additional nodes.
• The proposed method posses ses the mon otonic convergence property with the decreasing time steps.
• The numeric al dispersion error can be significantly suppressed.
