“…As laminated composite materials are being used more frequently in the repair and strengthening of structures, response of this type of structure has received resurgent interest in recent years. Numerical methods, especially finite element (FE) method, have been a valuable tool in design and study of aeroelastic stability of structural elements and complex aerospace structures [5]. Vibration behavior of metallic plates repaired and strengthened with single-sided and double-sided composite patches was investigated by Rezaeepazhand and Sabouri [6,7].…”

The performance of damaged metallic plates reinforced with fiber-reinforced polymer composite materials (composite patches) is presented in this study. A square aluminum plate with a central cutout is considered as a damaged structural element. Numerical studies using commercial finite element code were conducted to investigate the effects of variation in patch lamination parameters on flutter velocity of the repaired plates. The various laminate parameters such as fiber angles and stacking sequences are considered in this study. The results presented herein indicate that, for flutter pressure of a repaired metallic plate with central cutout, a set of laminated composite patches with different number of plies and stacking sequences can be found, which improve flutter pressure of damaged plates.
