Abstract
The concept of a loading surface corresponding to creep strains is formulated similarly to how the concept of a loading surface corresponding to plastic strains is introduced. An equation for the loading surface corresponding to creep strains is obtained. It is proven that, in the absence of viscosity of the material, the equation of the loading surface corresponding to creep strains coincides with the equation of the loading surface corresponding to plastic strains.
