Abstract
Some effects of the stress-strain state, such as vibration creep, creep acceleration and ratcheting, observed and studied in the experimental mechanics of a deformable solid, are proposed to be modeled on the basis of constitutive relations implemented in tensor nonlinear viscoelastic models of the Maxwell type. The apparatus of isotropic tensor functions is used, depending on two symmetric tensor arguments. Examples are given of a complex stress state in a tubular sample, when there is a significant disproportionate increase in time of the axial component of deformation under the combined action of constant axial and oscillatory shear loads compared to the case of action of only axial load. The concepts of generalized and combined ratcheting under complex stress conditions are introduced.
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.
