APPLICATION OF FINITE ELEMENT ANALYSIS FOR SOLVING ISSUES OF FORECASTING BEHAVIOR OF VERTICAL VESSELS WITH PROCESS PIPING IN EMERGENCY SITUATIONS
Second half of the twentieth century became the time of active development of such applied academic discipline as industrial safety. First of all it was connected with the industrial-production growth, increase of its concentration, complication of technologies, application of wide range of new types of substances taking part in processing procedures and so on. All of this resulted in a situation where occurring technogenic accidents possess increasingly cata.
Accidents at the enterprises of oil and gas industry usually result in high vol-ume emissions of explosion and fire hazardous substances which generate fuel-air mixture clouds, petroleum products spills and as a result – fires, explosions, failure of vertical vessels and whole installations.
Nowadays issues related to practical calculation of accidents consequences, taking into account dynamic factors affecting strength and stability of structures under the influence of external factors, including explosion, are still poorly covered.
Performance of precise numerical experiment can significantly improve safety of the facility and save time and resources, required for carrying out live experiments, for designing new facilities, moreover it can reduce accident risk of existing facilities.
The article contains development with the application of numerical methods of the model of dynamic behavior of vertical vessel with process piping under the influence of shockwave effect in full three meters positioning and taking into account multifactorial loading and detalization of object geometry. Typical changes of plastic strains distribution in different elements of the considered system, depending on the direction of shockwave effect, were analytically obtained.
