(A,B) Transmural distribution of circumferential Cauchy stress \({\sigma }_{\theta }\) (A) and radial Cauchy stress \({\sigma }_{r}\) (B) across the normalized vessel wall; (C,D) Transmural distribution of circumferential stretch ratio \({\lambda }_{\theta }\) (C) and radial stretch ratio \({\lambda }_{r}\) (D) across the normalized vessel wall at \({\lambda }_{z}\) of 1.3 and transmural pressure of 80 mmHg. The results were computed when the 3D active strain energy function was applied to the IM layer and the 3D passive strain energy function was applied to the entire vessel wall (h = 0.22 mm with the thickness of IM layer equal to \(\frac{h}{2}\)).
