Abstract
The paper presents the results of two directions of the study of the stress-strain state in the vicinity of singular points of elastic bodies, namely: change of the type of boundary conditions; edges of the contact surface of different materials. The result of the first direction is the solution of elasticity theory problems in the vicinity of singular points, from which the possibility of infinite stresses at these points follows. The second direction is associated with the analysis by numerical and experimental methods of the stress state in the vicinity of singular points, which, as a rule, occur when modeling real objects and are potential stress concentration zones. The main content of the article is to establish, based on a comparison of the results of the two directions, the relationship between variants with a minimum stress level in the vicinity of singular points with the results on the nature of the stress singularity at these points.
期刊介绍：
Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
