NUMERICAL ASSESSMENT OF THE SELECTED SUPPORTING ELEMENT CARRYING CAPACITY OF CRITICAL INFRASTRUCTURE FACILITY / SZACOWANIE NUMERYCZNE NO?NO?CI WYBRANEGO ELEMENTU KONSTRUKCYJNEGO OBIEKTU INFRASTRUKTURY KRYTYCZNEJ

摘要

Issues related to critical infrastructure safety is highly demanding in aspect of newly projected systems. In this paper a problem of modeling and simulation of the supporting structure behavior of critical facility (without or with proposed protective cover) loaded with a shock wave is presented. Authors assume that two different phenomena will be responsible for minimization of shock wave effects: flow around cylindrical panel and energy absorption by panel structure. In this paper research focuses on the description and analysis of the process of explosion near the supporting elements and the blast interaction with the structure.
