Abstract:

Minimum-weight shapes of head closures for cylindrical pressure vessels are derived. Head configurations, weights, and membrane stresses are derived for thin-shell heads of isotropic materials with uniform internal pressure by restricting the knuckle shear stresses to constant values andor by minimizing the weight of prescribed-shape heads. Torispherical, ellipsoidal,AND CONSTANT-SHEAR-STRESS HEADS WITH CONSTANT AND VARYING THICKNESS ARE INVESTIGATED, WITH CONSTANCY OF ENCLOSED VOLUME AND SUPPORTING STRUCTURE BEING CONSIDERED. This study resulted in certain highly efficient shapes weighing up to 11 less than the corresponding hemispherical capping closure. Author
