In this paper a physically based and deterministic design procedure for spherical shells
under external pressure is introduced. Within the new design concept the membrane energy …

For the design of thin-walled spherical shells under external pressure empirical knockdown
factors are applied. These knockdown factors are based on experimental results from the …

Strain gradient plasticity phenomenon in the parent material (PM), heat affected zone (HAZ)
and fusion zone (FZ) of butt and lap joint of shielded metal arc welded AISI A36 steel is …

Buckling of externally pressurized torispheres having the same mass, external surface, and
material properties with uniform and stepwise thickness was studied. Three stepwise …

A machine learning (ML) method is proposed for buckling design of internally pressurized
torispherical heads, and geometric imperfection (GI) generated in the fabrication process is …

Tori-spherical shells are often used as enclosures of pressure vessels in ocean and civil
engineering. When subjected to external pressure, these thin-walled shells are prone to …

Compressive stresses present in the knuckle of ellipsoidal heads subjected to internal
pressure. The presence of such stresses may make buckling possible. In this study, we …

The bottom head in the residential electric water heater tank is an externally-pressurized,
thin-walled, torispherical structure. In this paper, the buckling behavior of the bottom head …

As the main pressure components of pressure vessels, the mechanical performance of
cylinders and heads affects the normal operation of pressure vessels. At present, no unified …

Dual-phase (DP) steels have been widely applied in automobile industry, and are famous
for continuous yielding in their corresponding stress-strain curves. The appearance of yield …
