Description
Summary:At present many plasticity problems do not have a reliable solution. It is connected to the fact that in the theoretical calculations, based on the classical plasticity theories, a complexity of the process of loading of body is not considered. Sometimes this leads to significant errors. For plasticity with scleronome constraints (metals, alloys, etc.) at isothermal processes the functionals that were described of loading process do not depend on time. However the functionals in constitutive relations in plasticity should be also dependent on loading history. At practice, they can be found for some classes of complex loading processes experimentally. Some fundamental properties of functionals via experimental investigations of materials are presented here.
