Sentence examples for compressed shells from inspiring English sources

Stay-in-place formwork is often used to accelerate the construction of structural elements such as flooring, concrete bridge decks and compressed shells.

The fort was built of coquina, a soft local stone made of compressed shells.

Low values of the parameter S correspond to oblate elliptical openings, giving rise to compressed shells.

Both lineages are also characterized by an increasing adult size and an increasing oxyconic character of the shell (more compressed shell and/or more acute venter; Figures 5 and 6).

Among the documented parallel morphological evolutionary trends, the most important are: increasing involution (more tightly coiled whorls toward a closed umbilicus); development of an oxyconic shell (more compressed shell and/or more acute venter); larger shell diameters (body size); and the terminal acquisition of an umbilical lid.

In the case of axially compressed conical shells, no clear evidence of the existence of simultaneous buckling modes can be found in the literature.

For this purpose, the well known graphical method of predicting buckling loads, i.e., the Southwell's nondestructive method for columns is analytically extended to spherical shells and a new formula is derived for the critical buckling load of uniformly compressed spherical shells.

Then effects led by three patterns of thickness variations on the buckling of axially compressed cylindrical shells, which are axisymmetric modal, local and stepwise variable, are, respectively investigated.

In the present paper, within the framework of the so-called classical theory (linear bifurcation eigenvalue analysis), the buckling behaviour of axially compressed cylindrical shells is firstly reviewed.

Three mathematical examples, one numerical example and one complex engineering problem, i.e. axially compressed stiffened shells in launch vehicles, are utilized to demonstrate the robustness and efficiency of the proposed method by comparison with other existing methods.

In this work, we study the influence of imperfections on the critical buckling of axially compressed cylindrical shells for different geometries and composite materials (Glass Fibre Reinforced Polymer (GFRP), Carbon Fibre Reinforced Polymer (CFRP)) and aluminium using the finite element (FE) analysis.
