edge of full plasticity, the law of plastic current, an edge singular, criterion of a limiting status.

It is shown, that the edge of full plasticity is formed by an edge singular deviator functions on полуплоскостях frequency rates of an intermediate main stress and criteria of a limiting condition at extreme values of parameter Lode.
