Original Abstract

Multi-layer structure of the artery can have significant effects on the resulting mechanical behaviour of the artery wall. Separation of the artery into individual layers is sometimes performed to identify the layer-specific parameters of constitutive model proposed by Holzapfel (2000). Inspired by this single-layer model, a double-layer model was formulated and used for identification of material parameters from homogenized stress-strain data (of non-separated artery wall). The paper demonstrates that the layer-specific parameters of the double-layer constitutive model can be indentified without the need of artery separation. The resulting double-layer model can credibly describe the homogenized stress-strain behaviour of the real artery wall including large-strain stiffening effects attributed to multi-layer nature of the artery.
