Abstract Hanger installation is important in constructing self-anchored suspension bridges. The installation plan is obtained from comparative studies of concerned information in tentative construction steps. The comparisons are generally performed manually using detailed nonlinear finite element method (NFEM), particularly for those with 3D curved ...

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

A XY Spin Chain Models on Space Curves and Analogy with Kirchhoff Rods
2007A XY Heisenberg spin chain model with two perpendicular spins par site is mapped onto a Kirchhoff thin elastic rod. It is shown that in the case of constant curvature the Euler—Lagrange equation leads to the static sine-Gordon equation. The case of a double-helical DNA-like configuration corresponds to two interacting Heisenberg spin chains and the ...

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).

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

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.

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. All the bacterial
