On September 24, 2014, at the institute seminar the head of the “Creeping Theory” department doctor phys. math. sci. prof. L.Kh.Talybly will give a talk “Special theories of plasticity and strength at non-monotonic loadings.”
Qualitatively new theory of plasticity and strength of a body with non-monotonic loading were developed. Within the framework of these theories
a) A new definition of the relation of plasticity at the general non-monotonic loading were proposed;
b) A system of simple experiments to determine the material functions and constants that are included in the constitutive equations was formulated;
c) A new mathematical problem of plasticity was set;
d) methods have been developed to solve it;
e) A kinetic equation of damage to elastico-plastic bodies at non-monotonic loading was constructed;
f) The conditions of damage and strength of elastico-plastic bodies with an overall non-monotonic loading were obtained.
