Abstract: The method of analysis of spatial fields of stresses and velocities in pro-cesses of plastic flow is given, based on mapping of flow zones in deviator space of stresses. A generalized Mises flow function corresponding to numer-ous experimental data is taken as the loading surface. It is shown that the generalized Mises model is convenient for analysis of spatial deformation processes with the power of a special depicting parametric space. The numer-ical implementation of the method is illustrated by the example of plastic compression of a material under three-dimensional deformation conditions. It is shown that the distribution of stresses and flow rates depends on the current ratio of layer sizes during settling.
Keywords: plasticity, plastic flow, stress, flow rate, deformation, basic equations defining ratios, modeling, plastic compression.
