Deformation and Stress Distribution of Arterial Walls of the Aged

摘要

Deformation and stress distributions of arterial walls of the aged under the internal pressure are analyzed based on a fiber-reinforced three-layer composite hyper-elastic tube model within the large deformation hyper-elastic theory.Deformation curves and stress distribution curves are obtained through numerical computation.Effects of the residual stress,the modulus of the matrix,the distribution angle of the fibers and the fiber dispersion are discussed.
