- Abstract
- To design and estimate material failures of Type III pressure vessels, which have excellent stability and performance, various modeling techniques have been introduced. This paper provided a hybrid modeling technique composed of ply-based modeling for a cylinder part and laminate-base modeling technique for a dome part for enhancing modeling efficiency. The plybased modeling technique provided accurate ply stresses directly for predicting material failure,on the other hand, additional manipulations in stress calculations, which may cause some errors,were needed for the case of the laminate-based modeling technique. The ply stresses in fiber,transverse and in-plane shear directions were compared with the corresponding material strengths to predict material failure.
