Abstract

In this paper, we study the ultimate deformed state of an isotropic rod under the influence of external pressure and varying linearly along its generatrix. It is assumed that the rod rotates around its axis. The general equations describing the limiting state of rods under the influence of external pressure in a cylindrical coordinate system are considered. Integrals of relations describing the ultimate deformed state of the rod are obtained. The characteristics of the studied ratios and the envelope of the family of characteristics are found. The deformed state of a cylindrical isotropic rod with a circular cross-section under external pressure is determined.

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.
