An exponential constitutive model excluding fibres under compression: Application to extension–inflation of a residually stressed carotid artery
Li, Kewei; Ogden, Ray W; Holzapfel, Gerhard (Journal article; Peer reviewed, 2018)Detailed information on the three-dimensional dispersion of collagen fibres within layers of healthy and diseased soft biological tissues has been reported recently. Previously we have proposed a constitutive model for ... -
An arterial constitutive model accounting for collagen content and cross-linking
Holzapfel, Gerhard; Ogden, Ray W (Peer reviewed; Journal article, 2020)It is apparent from the literature that the density of cross-links in collagenous tissue has a stiffening effect on the mechanical response of the tissue. This paper represents an initial attempt to characterize this effect ... -
Modeling fibrous biological tissues with a general invariant that excludes compressed fibers
Li, Kewei; Ogden, Ray W; Holzapfel, Gerhard (Journal article; Peer reviewed, 2018)Dispersed collagen fibers in fibrous soft biological tissues have a significant effect on the overall mechanical behavior of the tissues. Constitutive modeling of the detailed structure obtained by using advanced imaging ...
