An improved analytical method to estimate three-dimensional residual stresses of the aorta

•Load-free condition in the residually-stressed state was properly incorporated.•Residual deformations in agreement with experiment.•Opening angles of each layer of the aorta incorporated as variables.•Patterns of residual stress and in vivo stress distribution was renewed.•Influence of the residual...
