Stress distribution in human artery based on several types of SEDF
Original language description
Two material models of an arterial wall based on hyperelastic approach are compared within a solution of a boundary value problem for thick-walled tube. Thick-walled tube, which is the computational model used here, was loaded by internal pressure p = 16kPa and axial pre-stretches z = 1.15, 1.3, 1.45. An influence of residual strains was included. It is shown that purely phenomenological model revealed circumferential Cauchy stress distribution in the range of supposed physiological values. Structuralmodel based on a fiber-reinforcement is significantly more compliant than phenomenological one. Moreover, the residual strains are necessary in the structural model to obtain physiological values of circumferential stress. An influence of an helix angle,which is a structural parameter, on the stress distribution was determined.
