Computer modeling of strain process of flexible rods with nonlinear and viscoelastic characteristics

Abstract

A computer model is a software implementation of a mathematical model, supplemented by various utility programs. A computer model exhibits the properties of a physical model when its abstracts components — the programs — are interpreted by a computer. In addition, a computer model, as a physical device, can be the part of test benches, virtual laboratories. Computer simulation allows without significant difficulties to modify mathematical models, which are the basis for obtaining results with a high degree of accuracy. In the article was considered the application of the developed methods for predicting nonlinear viscoelasticity of flexible rods under various loading conditions based on creep curves is possible only in the case of finite strains Rod oscillations with viscoelastic and nonlinear characteristics are considered in this paper. From the point of view of practice, it is interesting to study the oscillations of flexible rods (yarn) when the rod receives excitation depending on the acting dynamic loads in the form of a real oscillogram.
