Computational investigation of wave processes in perforated deformable media

The extremely actual problem of security of housing and industrial constructions by action of intensive dynamic loadings due to man-caused and natural catastrophes (explosive loadings, seismic activity, falling of airplanes and elements of orbital apparatus, acts of terrorism etc.) is addressed. Computational solution of the problem permits to give quantitative evaluation of durability and safety of buildings, that is to forecast the position and size of probable destruction area depending on intensity and character of influence, place of dynamic loading application and geometry of building, mechanical and thermophysical properties of constructive materials. Hyperbolic partial derivative system of equations from the deformable solid body mechanics was chosen as the mathematical model of construction materials [2, 3]. The Grid-Characteristic method [1] was used for the computational solution of the model.
