| Abstract |
The problem of a symmetric flow past a cone is considered
for a dense medium with an attached shock wave. The medium is
described by the state equation for a fluid with a nonlinear
compressibility diagram reflecting the actual behavior of soft soil
subjected to intensive loads. Plastic resistance to shear deformation
is taken into account only on the surface of the cone in
order to calculate the correction to the resistance. We examine critical
values of the Mach number and those of the shock wave angle corresponding
to the shock wave separation regime and we describe the resistance
coefficient and the nondimensional pressure as functions of the cone
angle and the Mach number. The results are compared with the solutions
obtained under the assumption that the medium beyond the shock wave front
is incompressible, the cone is thin, and the Mach number is
very large. An estimate is obtained for the penetration depth of a
cone of finite length in the regime under consideration. |
