| Abstract: | Using material formulation method, and choosing initial configuration as reference , the viscoelastic large deformation constitutive relation and the finite element equations denoted by the Kirchhoff stress and Green strain are derived. The equation is solved by use of the Total Lagrangian incremental approach. Satisfactory results are obtained. |
