DEFORMATION OF RODS WITH SMALL BENDING STIFFNESS
The Quarterly Journal of Mechanics and Applied Mathematics, 1993The author considers singular perturbations of problems in which the rod is replaced by a string with no resistance to bending. The general theory of singular perturbations for boundary value problems for nonlinear systems of ordinary differential equations is applied, and the obtained approximate solution consists of an interior approximation of the ...

A surface with stress, extensional elasticity, and bending stiffness
Soft Matter, 2019We demonstrate that the surface of a commonly used polydimethylsiloxane formulation (PDMS, Sylgard 184) treated by ultraviolet ozonolysis (UVO) has significant surface stress, considerable extensional elasticity (the “Shuttleworth Effect”), and surface bending elasticity.

Bending Stiffness of Unilateral and Bilateral Fixator Frames
Clinical Orthopaedics and Related Research, 1983The structural and geometric fixator properties that best neutralize the prevailing anteroposterior and transverse bending moments at a tibial fracture site were analyzed in anatomic specimens. Clinically and mechanically, anterior unilateral frames were most effective, particularly when applied with relatively stiff components with a maximal spread ...

Vibration of elevator cables with small bending stiffness
Journal of Sound and Vibration, 2002The effects of bending stiffness and boundary conditions on the lateral vibration of the stationary and moving hoist cables are investigated. The role of the trial functions in the approximate methods is examined. The optimal stiffness and damping coefficient of the suspension of the car against its guide rails are identified for the moving cable.

Theoretical Calculation of Bending Stiffness of Alveolar Wall
The Journal of Membrane Biology, 2013The bending stiffness of the alveolar wall is theoretically analyzed in this study through analytical modeling. First, the alveolar wall facet and its characteristics were geometrically simplified and then modeled using known physical laws. Bending stiffness is shown to be dependent on alveolar wall thickness, density, Poisson's ratio and speed of the ...

DNA Bending Stiffness on Small Length Scales
Physical Review Letters, 2008Bending properties of short (15-90 bp), double-stranded DNA fragments are quantified using fluorescence resonance energy transfer and small angle x-ray scattering. Results from both types of measurements indicate that short double-stranded DNA fragments exhibit surprisingly high flexibility.

Design of Variable Stiffness Composite Laminates For Maximum Bending Stiffness
10th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2004Benefits of directional properties of fiber reinforced composites could be fully utilized by proper placement of the fibers in their optimal spatial orientations. This paper investigates an application of a Cellular Automata (CA) based strategy for design of variable stiffness composite laminates for optimal bending stiffness.

Size effects of the bending stiffness of nanowires
Journal of Applied Physics, 2009This paper studies the size effect in the transverse deformation of nanowires or nanoropes subjected to flexural bending. Based on the classic strain-gradient theory, a continuum approach is proposed, in which the strain energy was expressed in terms of the linear strains and strain gradients, and two additional phenomenological internal parameters ...

Improving Bending Stiffness of Tensegrity Booms
International Journal of Space Structures, 2012There is a high interest in employing lightweight, low-cost, deployable structures for space missions. Utilization of tensegrity structures in space application is limited, due to their low stiffness, while a number of high stiffness-to-mass truss booms have been launched.

Analysis for Soil Reinforcement with Bending Stiffness
Journal of Geotechnical Engineering, 1992Soil nailing as a method of slope stabilization and repair finds widespread application despite the absence of a clear and unified design approach. The ability of soil nails to increase the shear strength of soil by acting under combined loading, namely, shear and tension, is one of the more controversial aspects of design.
