Dynamic Buckling load enhancement of Perforated Metallic Panels Reinforced with double sided Composite patches

The main objective of strengthening with laminated composite patches is to enhance the load carrying capacity of an existing structure or restore the damaged structures to its original performance condition. The use of advanced composite patches in increasing the dynamic buckling load of the perforated metallic cylindrical panel subjected to axial impact is presented in this study. Numerical study using commercial finite element code is conducted to investigate the effectiveness of the patch size and stacking sequences on the dynamic buckling load. The numerical results presented herein indicated that, dynamic buckling load of a perforated cylindrical panel can be significantly changed by using proper cross ply composite patches.
