Bu çalışmada, damarların lineer olmayan, anizotropik davranışını karakterize eden yeni bir bünye denklemi önerilmiştir. Damar çapı ile iç basıncı arasındaki ilişkiyi belirlemek genel kan akışı probleminin önemli bir parçasıdır. Bu ilişki insan torakik aortunda incelenmiştir. Literatürden elde edilen klinik veriler sadece iç basınç-çap ilişkisini sağlamaktadır. Bu veriler kullanılarak lineer olmayan regresyon analizi ile bünye denkleminin parametreleri belirlenmiştir

A New Approach on the Strain Energy Function for the Mechanical Behavior of Arteries

Öz

In this study, a new constitutive equation that includes the characteristic nonlinear anisotropic response of arteries is proposed. The measurement of the relationship between arterial diameter and arterial pressure is important part of the general problem of blood flow measurements. This relationship was examined in the human thoracic aorta. The clinical data that obtained from literature provide only a pressurediameter relationship. To determine the parameters of the constitutive formulations, nonlinear regression analysis was used on these data
