| Abstract: |
| By virtue of marriage of perturbation and boundary-finite element methods, A new approach is presented in this paper for solving the problem of linear creep.Due to the assumption that physical variables remain constant in a divided time interval is not adopted in the approach, the length of time step could be larger and computing accuracy could be increased.The perturbation form for boundary and boundary-finite element which includs reinforcement in it is established.Numerical validation of proposed approach against analytical solution is also favourablely given. |
