Abstract: The paper is concerned with simply supported shallow conical shells loaded through a central boss. The shell material is rigid-plastic and the relevant stress resultants are subject to a nonlinear ...

Abstract: A displacement bounding principle for continua loaded into the plastic range is presented. Use is made of Drucker’s inequality and the existence of a maximum complimentary work path between any ...

Abstract: The ASME Code specifications for unfired cylindrical pressure vessels are examined from the viewpoint of the lower bound theorem of limit analysis. The problem is formulated as a linear programming ...

Abstract: The yield surface for a shell of revolution which is loaded axisymmetrically and made of an anisotropic plastic material which obeys the maximum shear stress theory of Lance and Robinson is ...
