The paper presents a general and straightforward procedure based on the use of the strain energy density for deriving symmetric expressions of the secant and tangent stiffness matrices for finite element analysis of geometrically non-linear structural problems. The analogy with previously proposed m
Updating procedures are concerned with the construction of mass, stiffness and (possibly) damping matrices, near to some base matrices, which yield some response data close to some experimental values. One of the fundamental questions in updating relates to the criteria for allowable mass and stiffn
