| ABSTRACT In this study, effect of temperature, aspect ratio, number of layers and boundary conditions on critical buckling load of composite laminated plate was investigated numerically. Six different boundary conditions: (SSSS, SSFC, SSFS, SSFF, SSCC and CCFF), three temperatures (40C, 60C and 80C) and four aspect ratios (1, 1.3, 1.5 and 2) would consider. These variables were analyzed with different types of laminated plate (unidirectional, cross - ply and angle - ply). The thickness of the plate was changed by increasing the number of layers. The results showed that in the case of (a/b = 1 and θ = 0), and the temperature changed from (40C) to (80C), the maximum value of critical buckling load dropped by about (53 %) for (CCFF), while the minimum value of critical buckling load dropped by about (63 %) for (SSCC). Also, it was found that the maximum value of critical buckling load dropped by about (60 %) at the ply orientation (0/0) and (20/-20) at a/b = 1 and CCFF, while the minimum value drops by about (64 %) at the ply orientation (0/0), a/b = 1 and SSCC as the temperature changed from 40C to 80C. | ||
