BUCKLING ANALYSIS OF ANGLE PLY LAMINATED COMPOSITE PLATE (EXPERIMENTAL AND NUMERICAL APPROACH)

The main purpose of this study was to investigate the buckling behaviour of laminated composite plate both by experimental and numerical approach using ANSYS workbench software, and the results are compared to obtain the percentage error. In this study plates with orientation of 0/30, 0/45, 0/60 are being considered. We find that the buckling load was maximum for fibre orientation of 0/30 and minimum for orientation of 0/60. In this study, the plates having different aspect ratios of 0.20, 0.25 and 0.30 were also considered. We obtained increased buckling strength with increasing a/b ratios of 0.20, 0.25 and 0.30. It was seen that both the experimental and numerical study exhibited a good relation, the buckling load error for laminated composite plate was within 6%.
