To analyze the propagation dynamics of shock waves traveling through a one-dimensional chain of elastic beads lacking tensile restoring forces.
Numerically solved equations of motion for shock wave transmission through a chain of elastic beads modeled with no-tension elasticity.
Tracked the temporal evolution, peak amplitudes, and propagation velocities of the resulting wave pulses.
Shock wave propagation resolved into an ordered sequence of trailing peaks exhibiting systematically decreasing amplitudes and velocities.
Time-resolved analysis of the primary peak confirmed a recently proposed scaling law governing the decay of shock wave amplitude.
