i Schematics of a periodic layered composite bar with underlying unit cell of size D, subjected to a sinusoidal load P at \(x=0\) . ii Sinusoidal load P with amplitude \(E_{eff}\) over two periods, \(2t_d\). iii Normalised non-dispersive displacement response predicted by a standard elastic effective medium
