thick_wall_cylinder_tangential_stress
This model simulates the pressure and geometry resulting from changes in the internal radius of a thick-walled, distensible, isotropic, cylindrical vessel. Reference pressures and volumes are tunable. Stresses in the radial and axial directions are neglected and vessel wall material is assumed to be incompresible. An external function “ri” sets the inner radius values within the time domain.
