Abstract
Today’s world has a very urbanized structure – more than half the population of 6,8 billion people live in cities, and underground spaces are one of the most prerogative zones for city’s of modern civilization. Underground spaces have grown, along with the risk of terrorism and its organization. Therefore, it is very important to predict the dynamic impacts of explosives in underground spaces and the blast waves can be transformed into a loading of solid structures. In this paper, the impact of explosions and air strike waves is formulated and solved. The location of the center of explosion is very relevant. It appears that if the location is at the solid surface, this part can be up to 30% of the total energy (in soft solids). The variables to be calculated are the mass density of gas, the velocity of movements and the internal energy. The latter covers the influence of the gas pressure, being given for the adiabatic state. The air is linearly related to the internal energy of a unit mass of the gas, as is the density, while in the neighborhood of the source of explosion, the pressure changes nonlinearly with respect to the gas density.
