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

Identification of natural and technogenic seismic events by energy characteristics

One of the key problems of seismic monitoring is the identification of earthquakes and signals from technogenic sources detected by a network of seismic stations. In peacetime, technogenic events are mainly associated with industrial mining developments, however, with the beginning of russia's full-scale aggression against sovereign Ukraine, thousands of seismic signals from explosions as a result of missile, aircraft, artillery strikes were registered by the seismological network of the Main Center of Special Monitoring of the State Space Agency of Ukraine.

Seismicity of central part of Ukrainian shield in 2007 - 2013 period

Purpose. To perform a comparative analysis of record forms and earthquake spectrograms and explosions in quarries and mines what located in area of Kriviy Rih iron-ore basin (Kryvbas) for detection of seismic event signs of different nature this region with magnitude Mb ≥ 3,0 is the research object. Methods.

Using data of infrasound measurements in Ukraine for explosions and earthquakes identification

Purpose. The purpose of research is to determine the possibility of using of infrasound measurements that carried out in Ukraine for verification of registered seismic events and using of infrasound method as one of the criteria for their identification. Methodology. Registration of seismic and infrasonic signals carried out with using of geophysical networks of Main Center of Special Monitoring (MCSM). To register infrasound the small aperture acoustic group systems are used, allowing directional monitoring of events.
