ABSTRACT

Purpose is to study the impact of explosive waves in an urban environment using comprehensive numerical modeling. A series of simulations were conducted using ANSYS AUTODYN software, allowing us to accurately replicate the dynamics of explosive wave interactions with urban structures.

The methods used involves calculations through modeling and analysis of results. The obtained research results demonstrate that the application of numerical modeling with ANSYS AUTODYN allows for highly precise prediction of the influence of explosive waves on urban structures. These methods effectively model complex interactions between explosive waves and the urban environment, providing valuable information for safety measures and urban structure design.

Findings. Results demonstrate that the application of numerical modeling with ANSYS AUTODYN allows for highly precise prediction of the influence of explosive waves on urban structures. These methods effectively model complex interactions between explosive waves and the urban environment, providing valuable information for safety measures and urban structure design.

The originality lies in the combination of 2D and 3D modeling for a detailed analysis of explosive events in urban conditions, expanding existing knowledge about the interaction of explosive waves with urban infrastructure. Based on the obtained data, measures can be developed to enhance the safety and resilience of urban infrastructure in the event of explosive events, as well as to improve urban environment planning and protection.

Practical implementation. Based on the obtained data, measures can be developed to protect urban structures from potential explosive events, including the design of blast-resistant structures, optimization of urban plans considering potential risks, improvement of evacuation systems, and enhancing safety for the civilian population in densely populated areas.

Keywords: ANSYS AUTODYN, numerical modeling, explosion, urban environment, explosive load.
