Experimental Simulation of Deformation Effect Propagation Due to Explosion on the Surface of a Small-Scale Model

Abstract

The use of small-scale models is an important area of research today. An investigation is conducted on the response of a small-scale model’s vibrating surface. For this model, a small-scale surface explosion is used for loading. According to the article, the methodology includes procedures, model development, the explosive materials used, measurement and evaluation methods, software, and the technique used. Signal processing and response evaluation rely on a scientific method—the backward Fourier-transform principle—for frequency filtering. In this study, the simulation results are used to confirm the basic physical properties of the viscoelastic system. It is primarily investigated whether wave processes are confirmed on the new material. In terms of single wave propagation, the results summarize the characteristics of these waves (attenuation, velocity of propagation, etc.). Conclusions are targeted at the possibility of correlating three types of results: small-scale simulations, numerical simulations, and a real full-scale experiment.
