What Is The Physical Meaning Of A Stiffness Matrix To Be Singular? A stiffness matrix that describes the deformation of an elastic body will in general be singular. Because any simple translation has no impact on the stored energy of deformation. As well, a simple rotation will also leave the energy unchanged. Why is my

What Are The Properties Of Stiffness Matrix? A stiffness matrix, [K], relates point forces, {p}, applied at a set of coordiantes on the structure , to the displacements, {d}, at the same set of coordinates. The locations and directions of the point forces and displacements are called the coordinates of the structural model. What is
