Soil dynamics under underground explosion near the free surface

摘要

Basic aspects of soil dynamics under explosive processes in soil mediums are stated in this paper. Nonlinear equations of soil, as an elasto-plastic medium are being integrated in moving Euler-Lagrangian nets near the explosion charge and in motionless nets in the further zones. Equations of state of soil describe both the elastic behavior and nonlinear compressibility, volumetric and shear plasticity. Results of computational investigations of forming seismic waves on the considerable distance from the charge are described in this paper.
