Abstract: It is now a rather common approach to perform patient-specific stress analyses of arterial walls using finite-element models reconstructed from gated medical images. However, this requires to compute for every Gauss point the deformation gradient between the current configuration and a stress-free reference configuration. It is technically difficult to define such a reference configuration, and there is actually no guarantee that a stress-free configuration is physically attainable due to the presence of inter… Show more

“…As discussed in Mousavi and Avril, different material parameters for the media and adventitia render discontinuous circumferential and axial stresses at the interface between the media and adventitia, supported also by other studies . In addition to the different material parameters, it is required to introduce 2 deposition stretches for the elastin, one axial and one circumferential, which are calibrated to ensure (1) that the stresses in the wall of the artery balance the luminal pressure present in the reference in vivo diastolic configuration and (2) that the axial recoil of the artery upon excision is predicted correctly.…”

“…The important potential of the CMT has already shown for predicting the mechanobiological behavior of arteries based on anisotropic hyperelastic models . In the present paper, we combined for the first time the CMT approach with a damage model for predicting layer‐specific damage initiation in arteries during overpressure loading.…”
