The inflation of an ellipsoidal viscoelastic nonlinear membrane is described. The creep and relaxation phenomena are obtained for constant inflating pressures and constant deformations. The governing equations are written in terms of three new variables and are reduced to three partial differential integral equations. These equations are further reduced to three first-order ordinary equations with explicit derivatives by employing the trapezoidal rule for integration. The constitutive equations developed by Pipkin and Rogers are used.
