O operatorowym podejściu do formułowania zasad wariacyjnych dla ośrodków plastycznych
In the paper the application of a free variational principle is considered with regard to: 1) rate boundary-value problem of elastic-plastic solids; geometrical nonlinearity is taken into account; 2) plane flow of perfectly-plastic, compressible solids.
