Stiffness matrix and quantitative measure of formation rigidity

Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009
Rigidity of formation is an important concept in multi-agent localization and control problems. There are well-developed existing methods to test rigidity of a given graph. However, little work is done on quantitative measurement of formation rigidity.

Note on the normal form of a spatial stiffness matrix

IEEE Transactions on Robotics and Automation, 2001
There has been some recent interest in the problem of designing compliance mechanisms with a given spatial stiffness matrix. A key result that has proven useful in the design of such mechanisms is Loncaric's normal form. When a spatial stiffness matrix is described in an appropriate coordinate frame, it will have a particularly simple structure.

The role of matrix stiffness in regulating cell behavior†

Hepatology, 2008
Matrix stiffness (resistance to deformation), one of the many mechanical forces acting on cells, is increasingly appreciated as an important mediator of cell behavior. It regulates cell signaling broadly, with effects on growth, survival, and motility. Although the stiffness optima for different kinds of adherent cells vary widely, it is generally true

Rank and Degeneracy of Stiffness Matrix

1972
In order to determine the degree of degeneracy and the rank of the stiffness matrices let us consider the equilibrium of the system. Since the loads acting on the system are in equilibrium, the following equation must always be satisfied.

Assembling the System Stiffness Matrix

2016
Having decomposed the structures into nodes and elements, it is clear that knowing the nodal displacements will give us the internal loads in the elements. The displacements at the closed degrees of freedom are known, but we must still compute the displacements at the open degrees of freedom.

The stiffness of extracellular matrix in regulating cellular metabolism

American Journal of Physiology-Cell Physiology
Cells interact dynamically with the extracellular matrix (ECM), which provides both structural support and biochemical signals that regulate various cellular processes. Among these, the mechanical properties of the ECM, particularly stiffness, play a crucial role in governing cell differentiation, migration, and survival.

A Stiffness Matrix for the Analysis of Thin Plates in Bending

Journal of the Aerospace Sciences, 1961
A stiffness matrix is developed for an isotropic rectangular plate panel of uniform thickness for application to the analysis of thin plates of variable thickness in bending. The convergence characteristics of this matrix are demonstrated on simple problems with known exact, analog, and experimental solutions.
