INTRODUCTION:Living cells are known to exhibit an external stress-dependence of stiffness. Considering that cells and tensegrity structures share in common such a typical mechanical behavior, several authors have suggested to use tensegrity structures as comprehensive models of the cytoskeleton response. ...

Some of Buckminster Fuller's "Tensegrity" structures have fewer bars than are necessary to satisfy Maxwell's rule, and yet are not "mechanisms" as one might expect, but are actually stiff structures. Maxwell anticipates special cases of this sort, and states that their stiffness will "be of...
Stability conditions for tensegrity structures are derived based on positive definiteness of the tangent stiffness matrix, which is the sum of the linear a... JY Zhang,M Ohsaki - 《International Journal of Solids & Structures》 被引量: 91发表: 2007年 Investigation of clustered actuation in tenseg...

In such a structure, the tensegric shells can be a system of bars and a cable net, with the shell attaining its topology and stiffness when the bars are prestressed against the cable net. Advantages of such structures include the ability of tensegric shells to be self-sustaining, not ...
Tensegrity structuresare objects in which solid struts are linked by cords or cables. The tension of the cords is taken up by the struts which counteract the compressional force exerted by the cords. The structure takes on a shape in which all the forces are balanced. The artist Kenneth Snels...
Fuller described works of tensegrity as “self-tensioning structures composed of rigid structures and cables, with forces of traction and compression, which form an integrated whole.” He also believed that works of tensegrity were more natural than works of solely compression, as similar systems ...
We demonstrate that this model can naturally reproduce the universal power-law characteristics of cell rheology, as well as how its power-law exponent is related to cellular stiffness. More importantly, the power-law exponent can be quantitatively tuned in the range of 0.1 ~ 0.5, as found in ...
These H(T ) are ropelength-minimizers for the whole family, as long as the stiffness λ does not exceed 2, when circular arcs of larger radius would be needed. We will also develop an analog of our balance criterion for these other ropelength problems, and will see that all the H(T...
