| Abstract: | The Total Lagrange method is applied in the axisymmetric and large deformatinn problem. Meanwhile, the finite element analysis on the filament wound solid rocket motor case is carried out. Based on the above analysis, the software of axisymmetric finite element analysis for filament-wound composite case is produced, in which the winding condition, finite element grids generation, strain, stress and displacement analysis are performed and emulated. |
