Smooth mode decomposition: Theory and its applications in full-field output-only modal analysis

Our paper “smooth mode decomposition: Theory and its applications in full-field output-only modal analysis” was published by the Mechanical Systems and Signal Processing.

Highlights

  • Smooth mode decomposition (SMD) identifies the normal modes from system outputs.
  • The spatial differential operator endows SMD to identify smooth modal strucutures
  • SMD-identified modes approximate normal modes of systems with nonuniform parameters.
  • SMD identifies modes with high accuracy from temporally undersampled full-field data.
  • SMD is efficient for full-field dynamic analysis via digital image correlation data.
