摘要：

Biomechanical　characteristics　of　artery　vessel　have　been　investigated　in　morphology,　histology　and　mechanics　based　on　animal　experiments　and　mathematic　simulations.　Firstly,　the　axial　distribution　of　circumferential　residual　strain　and　opening　angle　was　analyzed　according　to　curve　length　transform　method;　Secondly,　the　method　of　building　and　loading　residual　stress　in　the　process　of　numerical　simulation　was　investigated;　At　last,　the　simulation　model　was　verified　to　be　reasonable　in　histology.　The　results　indicate　that　the　axial　distribution　of　elastic　fiber　in　histology　formed　the　distributions　of　residual　strain　and　opening　angle　in　mechanics,　which　results　in　the　ellipse　ratio　distribution　in　morphology.　The　mathematic　model　of　aortic　arch　with　residual　strain　is　not　only　feasible　but　also　reliable.
