Residual Force Method for damage identification in a laminated composite plate with different boundary conditions

The strongest point about damage identification based on the dynamic measurements, is ability perform structural health evaluation globally. Researchers in last few years payed more attention to indicators modal analysis using either frequencies, mode shapes, or Frequency Response Functions (FRFs). This paper presents a new application of cross-ply (0°/90°/0°) laminated composite plate Force Residual Method (FRM) indicator. Considering single and multiple damages with different levels. As well as investigating SSSS CCCC boundary conditions effect estimation accuracy. Moreover, white Gaussian noise introduced test challenge technique. results show that suggested FRM indicator provides accurate under conditions. Favouring condition than for 3% noise.
