- Abstract
Factors influencing the estimation of stress-strain states and characteristics of the durability and resource of critical threaded connections used in various fields of mechanical engineering is studied taking into account the conditions of their exploitation. It is shown that the durability and the resource of such threaded connections are defined using their static and cyclic damages under the action of a difficult combination of static, high-cycle, and low-cycle operational loadings. Both calculation and experimental research methods can be used for the estimation of local stresses and strains in thread turns and their redistributions in the loading process. Approaches based on the use of nonlinear deformation rules (including the elastoplastic area), regularities of accumulation of defects, and equations of nonlinear mechanics of the failure have to be the basis for the technique of the specified calculations. Questions of the damageability of elements of critical threaded connections taking into account their possible deformation in local zones (zones of the stress concentration) in the elastoplastic area are associated with the performance of the corresponding calculations of cyclic durability for areas of both multicycle and low-cycle fatigue.
