| Abstract: | FEM Of non-linear rheological problem is simply described in this paper. Based on non-linear rheological analysis, the time stop visco-elastic and visco-plastic initial stain method is presented. The three-dimensionalnon-linear rheological analysis program with wide suitability is studied and programmed, which can be applied toanalyzed the non-lineal rheological character of nuderground engineering problems. |
