Název v původním jazyce

Experimental identification of relaxation parameter from relaxation test of composite tube

Popis výsledku v původním jazyce

This paper is focused on the relaxation inflation tests of a composite tube manufactured from three layers. The first layer is formed from a thin latex tube, the second one, that increases a stiffness of specimen, is formed from a helically wounded textile rubber band and the third one is elastic matrix. Elastic matrix connects the first layer with the second one also. Experiments are based upon evaluation of recorded pressure responses to the stepwise increase of water volume inside the inflated pipe.The aim of experiments is to identify a relaxation parameter of a suggested viscoelastic constitutive equation, which is based upon the Haslach's principle of maximum dissipated energy during transition from a non-equilibrium towards the equilibrium state. Results obtained from simulations were compared with experimental measurements carried out with a viscoelastic tube and relaxation parameter was obtained.
