The present study is devoted to the computational problem of the residual stresses inside human blood vessel wall during atherosclerosis. The blood vessel (artery) wall is simulated by the thick-walled very long circular cylinder. The governing and constitutive equations of mechanics of surface growth solids are reminded for thick-walled solid case. The boundary value problem of the surface growth of an elastic thick-walled vessels is stated, solved and analyzed. The analytical solution is obtained in terms of velocities of stress strain state parameters. The condition of thickness allows us to study finite displacements of cylinder surfaces by means of infinitesimal deformations. The residual stresses caused by the influence of internal pressure are computed according to various initial growth tension in the adding layer. [ABSTRACT FROM AUTHOR] |
