FILAMENT WOUND CASE DEFORMATION ANALYSIS AND FAILURE EVALUATION

For matrix cracking and large deforming, the deformation of a filament-wound case is analyzed and calculated. The prediction and testresults are in agreement. In the deformation analysis, the failure evaluation has been completed for the filament -wound case. A good method is obtained for the failure evaluation of the filament-wound case. A theoretical basis is provided for working out rational water-pressure-testst andards.
