RESUMO

A model of an interaction of natural and artificial high-velocity particles with shielding constructions based on the dynamics of mesoparticles is presented. The processes of hard particle penetration into a soft barrier and the fracture of particles and shield elements were considered. It was found that a hard particle penetration of a thin barrier can be divided into three stages with different drag rates, whereas a high-velocity particle penetrates a thick barrier with a constant drag coefficient. On the other hand, when particle fracturing occurs, the contact area between a cloud of the front bumper and particle fragments and the rear wall is 100 times larger than a contact area between a particle and the front bumper.
