Wave reflection and cut‐off frequencies in coupled FE‐peridynamic grids

Summary Reflections are typically observed when pulses propagate across interfaces. Accordingly, spurious reflections might occur at the interfaces between different models used to simulate the same medium. Examples of such coupled models include classical continuum descriptions with molecular dynam...
