Improving Bending Stiffness of Tensegrity Booms

International Journal of Space Structures, 2012
There 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.

Tangent Stiffness Method for Biaxial Bending

Journal of the Structural Division, 1972
A method for computing generalized stress-strain relationships (moment-thrust-curvature relationships) for metal column sections in biaxial bending is described. The analytical formulation of the force-deformation equations in terms of the rate of change leads to a linear relationship between these quantities.

DEFORMATION OF RODS WITH SMALL BENDING STIFFNESS

The Quarterly Journal of Mechanics and Applied Mathematics, 1993
The 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 ...

Bending stiffness calculation for nanosize structures

Fatigue & Fracture of Engineering Materials & Structures, 2003
ABSTRACTAdvances in high technologies using nanometer‐size structures, such as carbon nanotubes, require calculation of mechanical properties for the objects of the nanosize scale level. Majority of the theoretical mechanical models for nanoobjects is based on the macroscopic equations of theory of elasticity.

Structural Assessment using identified Bending Stiffness

IABSE Congress, Chicago 2008: Creating and Renewing Urban Structures – Tall Buildings, Bridges and Infrastructure, 2008
<p>All Engineering structures are subjected to time dependent degradation processes. In order to allow a cost effective maintenance planning, it is necessary first to determine a structure’s condition and reliability profile respectively and second to extrapolate the acquired assessment indices into the future.

Bending stiffness of a graphene sheet

Physical Mesomechanics, 2014
The paper proposes a discrete mechanical model of monolayer graphene. A relation between parameters of the model and elastic characteristics of its equivalent continuum is derived by comparing the energy of small strains on micro- and macroscales. The relation allows one to determine the microscale interaction parameters from experimental data and ...

Bending stiffness of transversal isotropic materials

Composite Structures, 2017
Abstract Quasi-static bending of anisotropic and macroscopic homogeneous materials is studied as a two-dimensional elasticity problem. We extend a solution for beam-bending of isotropic materials found in the literature (Bower, 2010), where our selected form of a transversal isotropic material allows for a scalar Airy stress function which ...

Micro fabricated tunable bending stiffness devices

Sensors and Actuators A: Physical, 2001
This paper reports a device with tunable bending stiffness realized by microfabrication technology. Based on the newly proposed principles, two types of devices whose bending stiffness were controlled by electrostatic force and pneumatic force were fabricated.

Bending Stiffness of Unilateral and Bilateral Fixator Frames

Clinical Orthopaedics and Related Research, 1983
The 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 ...

Design of Variable Stiffness Composite Laminates For Maximum Bending Stiffness

10th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2004
Benefits 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.
