Age-related changes in longitudinal prestress in human abdominal aorta
Autor: Horný L.; Adámek T.; Žitný R.
(Springer Science+Business Media, 2013)Studies on the influence of aging on the longitudinal mechanical response of elastic arteries are rare, though longitudinal behavior may have a significant effect on pressure pulse transmission. Our study was designed to ... -
Analysis of axial prestretch in the abdominal aorta with reference to post mortem interval and degree of atherosclerosis
Autor: Horný L.; Adamek T.; Kulvajtova M.
(Elsevier Science, 2014)It is a well-known fact that the length of an artery in situ and the length of an excised artery differs. Retraction of blood vessels is usually observed. This prestretch plays an important role in arterial physiology. ... -
Axial prestretch and circumferential distensibility in biomechanics of abdominal aorta
Autor: Horný L.; Netušil M.; Voňavková T.
(Springer, 2014)Our study presents the results of an analytical simulation of the inflation-extension behaviour of the human abdominal aorta treated as nonlinear, anisotropic, prestrained thin-walled as well as thick-walled tube with ... -
Constitutive modeling of human saphenous veins at overloading pressures
Autor: Veselý J.; Horný L.; Chlup H.; Adámek T.; Krajíček M.; Žitný R.
(Elsevier Science, 2015)In the present study, inflation tests with free axial extension of 15 human vena saphena magna were conducted ex vivo to obtain data suitable for multi-axial constitutive modeling at overloading conditions (pressures up ... -
Effect of axial prestretch on inflation instability in finitely extensible thin-walled tube
Autor: Horný L.
(Czech Technical University - Fac. of Mechanical Engineering, 2014)Mechanical response of elastic materials undergoing large deformations exhibit several kinds of a loss of stability. Such a situation may occur, for instance, when a thin-walled cylinder is inflated by an internal pressure. ... -
How does axial prestretching change the mechanical response of nonlinearly elastic incompressible thin-walled tubes
Autor: Horný L.; Netušil M.
(Elsevier B.V., 2016)An analytical model of an incompressible thin-walled closed tube was used to simulate the mechanical response of an initially prestretched tube to internal pressure. Four different situations were considered: (I) a ... -
Limit point instability in pressurization of anisotropic finitely extensible hyperelastic thin-walled tube
Autor: Horný L.; Netušil M.; Horák Z.
(Elsevier Science Publishers B.V., 2015)Mechanical responses of materials undergoing large elastic deformations can exhibit a loss of stability in several ways. Such a situation can occur when a thin-walled cylinder is inflated by an internal pressure. The loss ... -
Limiting extensibility constitutive model with distributed fibre orientations and ageing of abdominal aorta
Autor: Horný L.; Netušil M.; Daniel M.
(Elsevier Science, 2014)Our study investigates three hyperelastic nonlinear constitutive descriptions for inflation-extension behavior of human aorta in the context of aging. The new, finitely extensible anisotropic model with the dispersion of ... -
Preservation of tangent modulus of pericardial tissue during cold storage
Autor: Gultová E.; Horný L.; Chlup H.; Žitný R.; Adámek T.; Kulvajtová M.
(Taylor & Francis, 2013)We have performed uniaxial tensile tests with human pericardium in order to identify the effect of a storage time on the passive mechanical response. Mechanical response was modelled using simple Fung´s type form of the ... -
The sustainable release of Vancomycin and its degradation products from nanostructured collagen/hydroxyapatite composite layers
Autor: Suchý T.; Šupová M.; Klapková E.; Horný L.; Rýglová Š.; Žaloudková M.; Braun M.; Sucharda Z.; Ballay R.; Veselý J.; Chlup H.; Denk F.
(Elsevier B.V., 2016)Infections of the musculoskeletal system present a serious problem with regard to the field of orthopaedic and trauma medicine. The aim of the experiment described in this study is to develop a resorbable nanostructured ...
