It is presented the analyses of a plane slab subjected to an uniform load, with the help of the finite differences numerical method. The problem, that summarizes at determining the stresses in certain points of the slab (assigned at the beginning of the calculus), can be solved using the plane elasticity equation.

This paper presents in a synthetic way the most important characteristics of an explosion and the most used empirical formulas for calculus of the blast wave parameters, in the general case of an air explosion. The paper also presents some numerical models and the newest procedures used for blast wave parameter and effect calculus upon structures.
