Dynamic model of curved rods

2000
The dynamic model of curved rod is obtained as an approximation of oscillations of three-dimensional curved rod--like linearized elastic body. The corresponding convergence result is stated.

Theory of the influence of changes in salt concentration on the configuration of intrinsically curved, impenetrable, rod-like structures modeling DNA minicircles

International Journal of Non-Linear Mechanics, 2010
Abstract DNA molecules in the familiar double helical B form are treated here as though they have rod-like structures obtained by stacking the nearly planar base pairs comprising them one on top of another with each rotated by approximately one-tenth of a full turn with respect to its immediate predecessor in the stack. As each base in a base pair is

Discrete Cosserat Rod Models Based on the Difference Geometry of Framed Curves for Interactive Simulation of Flexible Cables

2017
For software tools currently used in industry for computer aided design (CAD), digital mock-up and virtual assembly there is an increasing demand to handle not only rigid geometries, but to provide also capabilities for realistic simulations of large deformations of slender flexible structures in real time (i.e.: at interactive rates).

The energy of naturally curved elastic rods with an application to the stretching and contraction of a free helical spring as a model for DNA

The Journal of Chemical Physics, 2015
We give a contemporary and direct derivation of a classical, but insufficiently familiar, result in the theory of linear elasticity—a representation for the energy of a stressed elastic rod with central axis that intrinsically takes the shape of a general space curve.

A Novel Approach to Modeling Coronary Stents Using a Slender Curved Rod Model: A Comparison Between Fractured Xience-Like and Palmaz-Like Stents

2009
We present a novel mathematical model to study the mechanical properties of endovascular stents in their expanded state. The model is based on the theory of slender curved rods. Stent struts are modeled as linearly elastic curved rods that satisfy the kinematic and dynamic contact conditions at the vertices where the struts meet. A weak formulation for

The grivet monkey as a model for study of vaginitis. Challenge with anaerobic curved rods and Gardnerella vaginalis.

Scandinavian journal of urology and nephrology. Supplementum, 1985
The grivet monkey was used as an experimental model for vaginitis. Gardnerella vaginalis was used for challenge in one monkey. G. vaginalis plus a long variant (LCR) of a hitherto unclassified anaerobic curved rod (CR) in another 2 monkeys, this LCR alone in 2, a short variant (SCR) of CR in 2, and G. vaginalis plus SCR in one monkey.
