Computational Simulation Model of the Contact Behavior of Fiber Reinforced Composites on the basis of Analytical and Semi Analytical Algorithms

Abstract

Analytical and numerical-analytical methods for simulating a plane axisymmetric contact behavior of an elastic pipeline section with an isotropic or orthotropic viscoelastic composite wrap considering the features of its mounting on a loaded or unloaded pipeline with or without tension have been developed. These methods allow analyzing the efficiency of repair works on different mounting modes and at various degrees of anisotropy of the viscoelasticity of the composite wrap. The methodology qualitatively differs from the previously created techniques by a complexity of the approach, a high speed, an automation of receiving the sought-for parameters and a possibility of the created models to consider the degree of anisotropy of viscoelasticity which differs from the degree of anisotropy of elastic properties. These advantages of the simulation model allow using it in the further computational intelligence algorithms as a standalone or integral part.
