Numerical Simulation of Drill-String Dynamics with an Initial Curvature
Applied Mechanics and Materials, 2015This work is devoted to modeling of nonlinear dynamics of the rotating drill-string taking into account initial curvature and finiteness of deformations. The drill-string is compressed by variable axial force. The case of flat bending of the drill-string with an initial curvature is studied, where drill-string considered as a one-dimensional rotating ...

The Effect of Initial Curvature
Aircraft Engineering and Aerospace Technology, 1937THE method given in “The Stressing of Rigid‐Jointed Frames” published in the Journal of the Royal Aeronautical Society for June, 1936, may be applied to the case of frames embodying initially curved members, as for example, monocoque rings.

Curvature tailoring of unsymmetric laminates with an initial curvature
Journal of Composite Materials, 2012An unsymmetric laminated composite having bi-stability is interesting as a morphing structure because it can sustain large deformation without energy supply and the deformed state is stable. Especially, inducing different curvature values at each stable state is important for the practical application of unsymmetric laminates. In this study, we propose

Influence of the critical curvature on spiral initiation in an excitable medium
Physical Review E, 1994Spiral waves are created in a Belousov-Zhabotinsky medium due to the presence of some inert obstacle placed into that medium. The eikonal equation, which is completely valid when the excitability of the system remains constant, is shown to be insufficient when media with different excitabilities are used, as predicted by Zykov's kinematical theory ...

Eccentrically Loaded Steel Columns with Initial Curvature
Journal of the Structural Division, 1967The behavior of eccentrically loaded wide-flange columns with initial curvature is studied. The flange elements of the column section are assumed to be thin in comparison with the depth of the section. The moment-curvature relationship based on this assumption is derived for an elastic-perfectly plastic material, and is subsequently extended to include

On the parametric excitation of a tensioned bar with initial curvature
International Journal of Mechanical Sciences, 1980Abstract The parametric excitation of a tensioned bar with initial curvature is discussed. A model for the behavior is developed and the nonlinear equations for determining the secondary and principal regions of resonance are derived. Solutions to the equations are obtained and amplitude vs frequency data are presented.

Effects of Initial Curvature on Column Strength
Journal of the Structural Division, 1970Herein the two types of initial curvature: initial curvature on maximum strength of columns of rectangular cross section, and initial curvature on the maximum strength of a column, are examined for various shapes of column cross section.
