Shape factors of cylindrical permeameters
Geomechanics and Engineering, 2011This paper presents an analytical solution for steady state flow into a close-ended cylindrical permeameter. The soil medium is considered to be uniform, isotropic, and of infinite thickness. Laplace equation is solved by considering rotational symmetry and by using curvilinear coordinates obtained from conformal mapping.

Shape factors of cylindrical piezometers
Géotechnique, 1980This Paper describes a liquid electric analogue model and a finite difference model used to establish reliable values for the shape factors of cylindrical piezometers with length/diameter ratios of up to 15. For piezometers with length/diameter ratios greater than 4, it was found that the shape factor is given with negligible error by the relationship:

Stability of ribbed cylindrical shells with a nonideal shape
International Applied Mechanics, 1999The paper treats the elastic orthotropic thin-wall cylindrical shell stiffened by longitudinal and transversal rigidity ribs. Under some additional assumptions a numerical method is proposed for the analysis of critical loads for the shells with initial imperfections. The technique takes into account the ribs distribution.

Ventricular Shape: Spherical or Cylindrical?
1998It has been a long time since Harvey, in 1628, understood that blood flows in a circle. Actually, he only postulated the capillaries (18). Concerning the forces that support flow, he only allowed the vis a tergo without the vis a fronte. It was only 200 years later (in 1843) that Purkinje understood both these last-mentioned forces and recognized the ...

Theory of adsorption of macromolecules in cylindrical pores and at surfaces of cylindrical shape
Polymer, 1982A rigorous theory of adsorption of a Gaussian chain of infinite length into cylindrically shaped pores and onto cylindrical surfaces of arbitrary diameter, D, has been developed for any energy of interaction −ϵ. The change in the conformational free energy of a chain arriving inside the pores from an unrestricted volume is proportional to (D∗)−2 (D∗ is

EXPLOSION WELDING OF CYLINDRICAL SHAPES
1969Abstract : A number of papers have been published in the open literature on the explosion welding of concentric cylinders and on the joining of tubes to tube plates. The paper attempts to provide a concise review of these contributions by discussing work performed by the authors and other investigators.

Shape factor for non-cylindrical nanowires
Physica B: Condensed Matter, 2008The concept of shape factor, originally for non-spherical nanoparticles, has been generalized to nanowires with non-cylindrical shapes. The new shape factor is defined as the total exterior area ratio of nanowires between non-cylindrical and cylindrical shapes in identical volumes, which equals one for cylindrical shapes and is larger than one for non ...

Journal of the Physical Society of Japan, 1987
The linearized Ginzburg-Landau equation for the order parameter of superconductors with cylindrical shape and of superconductors with cylindrical cavity is solved to obtain a numerical relation between the magnetic field H and the eigenvalue E when a magnetic field is applied parallel to the cylindrical axis.
