The investigation of the stress-strain state of special purpose capacities for storage of explosion and toxic substances under their heating

Using the method of mathematical modeling, as well laws thermodynamics, analytical dependences were obtained to study stress-strain state spherical tanks depending on different surface temperatures this structure. The calculations performed showed that radial stresses are insignificant compared tangential ones, which act tension. greatest absolute value is taken inner structure, acting in tension and outer – compression. investigation results presented graphically.
 Explosive toxic substances a major component military bases stored special-purposes tanks, namely one most common. As result sabotage or arson these there leak formation steam gas clouds can lead an explosion, significant thermal radiation, possibility infection equipment, territory, various objects vicinity accident, including personnel, makes it impossible conduct hostilities for long time.
 Analyzing experience accidents at similar facilities, several types gasholders during their depressurization possible, namely: flare, fireball, fire presence saturated explosive cloud. extraordinary places storage toxic, fuels lubricants, related violation exploitation, allows us conclude global problem today. Therefore, prevent explosion hazards, strength engineering structures contain quite high requirements. 
 One main tasks general safety ability timely warn accidental explosions building, explosion-proof structures, personnel nearby. impact temperature special-purpose due sabotage, natural factors abnormal cases characteristics type important, both theoretically practically.
