| Abstract |
A generalization of self-similar solutions of the axially symmetric problem
that correspond to the yield on a Tresca prism edge is considered. These
solutions have been obtained by Shield [1]. The search for new self-similar
solutions is based on the relationships of the spatial problem represented
in the isostatic coordinates, with the axial symmetry and the possibility
of the separation of an additional non-angular coordinate being taken
into account. It is established that the axially symmetric problem
of plasticity has a number of self-similar solutions in which the products
of powers of the isostatic coordinates play the role of self-similar
variables. For some specific values of the exponents occurring in the representation
of a self-similar solution, the order of the equations of the axially
symmetric problem can be reduced by one and the problem can thus be reduced
to one nonlinear time-varying first-order equation which then can be reduced
to an Abel equation of the first kind. The integral curves of this equation
are constructed within the natural domain. In the self-similar solution domain,
the maximum (minimum) principal stress is constructed numerically as a function
of the polar angle in the meridional plane. |
