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

Highlights

• Smooth mode decomposition (SMD) identifies the normal modes from system outputs.
• The spatial differential operator enables SMD to identify smooth modal structures
• 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.
