Experimental setimeted of the some parameters of the conveyor belts

Abstract

At present one of the most spread methods able to solve non-linear problems of the mechanics is theis the finite-element method. When solving problems of hyperelasticity by the finite-element method (FEM) for introducing the input materials' constants of the body investigated, best - thought-out Money-Rivlin's theory is used. It is the method describing the behaviour of hyper-elastic materials with large elastic (reversible) deformations. For the description of behaviour of the hyperelastic materials, can be used also the development from more members, comprising 5 or 9 materials' constants. The problem with the determining the hyperelastic materials' characteristics is one of the most important factors effecting the accuracy of the calculation result. The material's constants A and B are det-rmined experimentally from the practical tests, e.g.tensile, compressive or other and have to meet certain conditions. The paper shows the possibility how to determinate these matherials´ charakteris-tics and their verification by the mathematical model ANSYS.
