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

Geodynamic and geophysical effects in the physical models of interactions between the Earth’s structural shells

Perspectives of the creating of the new physical models concerning the structure of the Earth, their evolution and methodology of the structure classification and parameter measuring of the Earth’s physical fields are analyzed. It is pointed out that investigation of the deep structure, composition and geodynamics of the continental and oceanic lithosphere gives the possibility to distinguish the system connected with global processes of Earth’s development (rifts, uncompensated deeps, continents, oceans).
