| Abstract |
The stationary motion of an ideally plastic compressible material in a converging conical
channel is considered. It is assumed that the material obeys the Green’s yield condition and normality
rule. It is assumed that the maximum friction law is fulfilled on the contact surface of the material with
the channel wall. The Cauchy stress tensor as a function of the local density of the medium is determined by solving an ordinary nonlinear differential equation of the first order, and finding the density
is reduced to calculating a definite integral. Analytical dependences, which specify a two-sided estimate of the density and pressure in the channel, are obtained for arbitrary plastic moduli. The analytical results are compared with the available experimental data. |
