Two-Dimensional Modeling of Explosion Impulses on a Structure Using the Discrete Element Method

Explosive phenomena pose significant threats to structural integrity, necessitating accurate prediction models for designing resilient infrastructure.  Traditional computational approaches like CFD and FEM, while detailed, require substantial computational resources and specialized expertise.  This study presents an alternative approach using the Discrete Element Method (DEM) implemented through the Pymunk physics engine for 2D explosion modeling.  The developed method models explosions as radially distributed particles with initial impulses, simulating shock wave propa

RESISTANCE OF STRUCTURAL ELEMENTS OF CIVIL PROTECTION BUILDINGS AND STRUCTURES TO THE IMPACT OF AN EXPLOSION

The article presents the results of a comparison of the stability of the structural elements of the underground parking lot of an erected multistory civil building. The results of calculation of structural load-bearing elements (monolithic floor slab and pylons) to the impact of an explosion in the Lira CAD software with consideration of the requirements of the state Building standards of Ukraine are presented.
