Mathematical Modeling of Creep of Aluminum Alloy 1570P (Al-Mg-Sc System) Using Kinetic Physical-Mathematical Theory of Metal Creep
In the work with the purpose of determining the prospects of using the kinetic physical and mathematical theory of creep of metals for performing design calculations when creating new technology products, the results obtained in describing the theory of uniaxial creep processes of 1570P alloy under conditions of steady-state and abrupt changes in thermomechanical loading parameters are presented. It is established that the new physical and mathematical theory of creep of metals being developed, which, unlike the classical phenomenological theory, takes into account the structure of the metal and its change in the creep process, equally well describes the process under steady-state and non-stationary conditions of thermomechanical loading. The important role of the structural state of the metal on the creep process is shown. The main structural parameter determining the characteristics of the process is the scalar density of immobile dislocations.
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.
