摘要
•Residual deformations and material parameters acquired from the same aortic sample to ensure subject-specific residual stress.•Propose a framework combining experiment, analytics and numerical simulation to evaluate the subject-specific residual stress.•Experimentally-derived layer-specific residual deformations accurately replicated numerically with the proposed method.•Residual stress in aortic dissection numerically simulated and buckling behavior of intimal flap validated against experiment.
