Název v původním jazyce

Identification of relaxation parametr composite tube from fluid transient experiment

Popis výsledku v původním jazyce

This paper presents a fluid transient inflation experiments with a viscoelastic composite tube and its numerical simulation. Mathematical description of experimental setup (inflated tube, piping and pressurized vessel) is based on the windkessel model and a nonlinear viscoelastic constitutive model of the inflated tube, which is derived from the principle of maximised dissipated energy. The governing system of equations is solved by means of the implicit Euler method. Fluid transient simulation was usedfor relaxation parameter identification of the constitutive viscoelastic model of the specimen. The viscoelastic tube was tested by inflation and a fluid transient test. The tested tube had a composite structure with layer reinforced by fibre oriented in helical structure with limited extensibility. The purely elastic part of constitutive model was obtained from the inflation test. Results obtained from simulations were compared with experimental measurements carried out on a viscoelast
