“…A box (B) with dimensions of 25 × 27 × 45 cm was made from galvanized smooth sheet caliber 26 1 ; it was filled with fine sand reaching a total mass of 33 kg and was used to propagate five pendulum impacts across it. All impacts were induced using a 0.575 kg mass at an initial angle θ = 30 • with a pendulum (P) with 30 cm chord length.…”

“…Laser-based measurements have been widely used over the years with different arrays and applications; those optical systems can measure through destructive and non-destructive procedures [1][2][3][4]. This paper is focused on a non-destructive technique that helps to calculate the relative motion using a laser light reflection adopting an image-matching methodology.…”

We present a simple but accurate correlation between an experimental characterization and a simple analytical prediction of a wave propagation induced by the impact of a pendulum in a box filled with fine sand; this research is based on optical measurements and was carried out using the digital image correlation technique to determine the motion on the surface of the box visually observed by the reflection of the laser. We suggest that the reaction to the impact in the body will be similar to an equivalent damped mass-spring system, obtaining an average error of 3.67208 × 10 −4 .
