| Abstract: | Based on the Total Lagrangian approach and the integral constitutive relation, the viscoelastic large deformation incremental variational equation is derived, and the finite element program of axisymmetric problems is written. By using this program the bore change of propellent of nozzleless rocket under the action of both the internal pressure and burning is dealt with in detail. |
