20.500.12556/DKUM-66838 An approach to consider the arterial residual stresses in modelling of a patient-specific artery In this work, the residual stress state of a human common carotid artery is predicted using the so-called thermomecha- nical analogy approach. The purpose of the approach is to enable consistent mapping of residual stresses and the respec- tive configuration from a circular arterial segment to a patient-specific arterial geometry. This is achieved by applying proper volumetric dilatations to the actual arterial stress-free in vivo geometry, which makes use of the analogy that states that the bending stresses can be obtained on an equivalent manner by applying proper thermal dilatations. The common carotid artery data are obtained in vivo from a healthy 28-year-old man using non-invasive methods. The pre- dicted residual stresses of the common carotid artery are in good quantitative agreement with the data from prior work in this field. The approach is validated by predicting the common carotid artery zero-stress state configuration, where a sector-like (cut-open) state is obtained. With this approach, it is thus possible to predict the residual stresses as well as the configuration of patient-specific arterial geometry without the need to model its cut-open zero-stress configuration. patient-specific artery common carotid artery residual stresses arterial zero-stress state thermomechanics finite element method človeška arterija skupna karotidna arterija zaostale napetosti breznapetostno stanje arterij termomehanika metoda končnih elementov nega bolniki true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-07-12 12:04:46 2017-07-12 12:05:56 2022-08-01 13:13:45 2021-05-02 03:14:35 2016 0 0 str. 1-19 št. 11 Letn. 8 Nov. 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1687-8140 531:616.13(045) 13232662 15115035 10.1177/1687814016679312 1687-8140 URN:SI:UM:DK:JXZKLJLI Advances_in_Mechanical_Engineering_2016_Urevc_et_al._An_approach_to_consider_the_arterial_residual_stresses_in_modelling_of_a_patient-sp.pdf Advances_in_Mechanical_Engineering_2016_Urevc_et_al._An_approach_to_consider_the_arterial_residual_stresses_in_modelling_of_a_patient-sp.pdf 1 964EC99392686FCF0E7132BDD7E7D5AC 14ac2fef8fe63a8cbbb8fe599b2d2508961dbe0ffda690de2c8ae97604d8ff1d 67bae899-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/3a68adeb-da6b-41eb-8fea-8697df5cffc5 https://dk.um.si/Dokument.php?lang=slv&id=114095 http://journals.sagepub.com/doi/abs/10.1177/1687814016679312 1 https://dk.um.si/Dokument.php?lang=slv&id=114094 Fakulteta za strojništvo 0 0 0
