RESISTANCE OF TRANSPARENT STRUCTURES TO EXPLOSION INFLUENCES. OVERVIEW OF RESEARCH METHODS AND ANALYSIS OF INDIVIDUAL RESULTS
Abstract
The paper analyzes the potential of numerical modeling of the destructive impact of explosions from the point of view of its application to enclosing structures (including translucent ones). For the most common methods, a brief comprehensive theoretical basis with requirements, implementation and corresponding examples of results is given. In addition, the interpretation of the measurements is given. Separate simplified mathematical models, basic discretization schemes of the obtained values of the determining variables and calculation results are presented in combination with abbreviated descriptions of the main parameters of the materials of the fencing structures.
After the blast wave modeling process, it is necessary to estimate the response parameters of the translucent structure and the corresponding error in determining the factors affecting it. Recommendations from the above standards, based on the definition of a specific variable representing the structural deformation of the structure, should be applied.
The determination of the critical pressure for a specific structure is tied to the determination of the critical distance at which the structure cannot withstand the destructive impact of the shock wave.
The work was carried out with the assistance of the National Research Fund of Ukraine. The materials of the article contain the scientific results obtained as part of the implementation of the project No. 208/0172 "Aerodynamics, heat exchange and innovations to increase the energy efficiency of window structures and their use for the reconstruction of war-damaged buildings of Ukraine" competition "Science for the reconstruction of Ukraine in the war and post-war periods".
