This paper presents the optimization, simulation and practical application of operating parameters(load carrying capacity, friction forces, friction coefficient, wear) for hydrodynamic intelligent articular and artificial bio-bearing joints with curvilinear nano-shaped surfaces. One of the reason of such bone head and endoprosthese profile is that this profile contributes to the variation (an increase or decrease) the memory joint capacity. Such properties are very important and required in human joints. A general theory of materials with memory is the theory developed by Noll and Koleman. The simple solid body and liquid theory presented in this paper is based on the assumption that stress is defined by a whole deformation history. The changes of bio-bearing superficial surfaces presented in this paper are described by the process of changes of mass of a body system defined by non-Newtonian synovial liquid properties and its genetic (congenital) factors, which depends on epigenetic (environmental) factors (temperature, mechanical stress and strain, internal and external physical fields, etc.). Scientific problems considered in the paper are mainly focused on comparisons and practical applications of tribological processes, which occur during fluid flow around cells lubrication on the nano-surfaces in nano-bearings, as well as surfaces of bio-bearings.
