Shell foundations are often used to raise the carrying capacity of a structure on weak soils. In cases where large superstructure loads must be transferred poorer soils, shell more cost-effective than ordinary shallow foundations. Advances in study and design shell-type have shown their superiority over traditional footings The current aims investigate shape’s influence ultimate load capacity. ...

On wave-swept rocky shores, limpets are subjected to water velocities in excess of 20 m s(-1), which may impose large hydrodynamic forces. Despite the extreme severity of this flow environment, predictions from conical models suggest that limpets' shells are typically far from the optimal shape that would minimize the risk of dislodgment, a deviation that is allowed by the high tenacity of the ...

In the present work, a study of thermoelastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient and non-uniform internal pressure is carried out. The formulation is based on first-order shear deformation theory (FSDT), which accounts for the transverse shear. The governing equations, derived using minimum total potential energy principle, are solved, usi...

SUMMARY This Report considers theoretically and experimentally some of the problems associated with the flexure of two unequal cylindrical shells Joined by a conical frustum. Particular attention is given to the determination of the overall flexursl stiffness of the conical frustum and to structural design considerations associated with the provision of a separation capability in the frustum. T...

Autocoptis paulsoni n. sp. is described from Haiti. It is characterized by its large size, its cylindrical-tapered shape, its fine costate sculpture on the teleoconch, a distinct but weak circum basal keel and its abbreviate conical juvenile shell. It is most similar to Autocoptis gruneri (Dunker 1844), which is redescribed, and its distribution is reviewed. The taxonomic status of the genus Au...
