Abstract This paper provides a model updating approach to detect, locate, and characterize damage in structural and mechanical systems by examining changes in measured vibration responses. Research in vibration-based damage identification has been
rapidly expanding over the last few decades. The basic idea behind this technology is
that modal parameters (notably frequencies, mode shapes, and modal damping) are
functions of the physical properties of the structure (mass, damping, and stiffness).
Therefore, changes in the physical properties will cause changes in the modal properties which could be obtained by structural health monitoring (SHM). Updating is a
process fraught with numerical difficulties. These… More >
