| Abstract |
The results of numerical studies of wave processes accompanying normal impact and penetration of a cylindrical-conical body into homogeneous or layered frozen soil with the influence of the finite frost penetration depth taken into account are presented. Frozen and soft soils are modeled by Grigoryan's compressible medium with irreversible bulk and shear deformations. The influence of the frost boundary on the wave formation and penetration parameters is analyzed. The results of numerical computations are compared with known experimental data. |
