| Abstract | ||
| The determination of critical buckling load of composite plate is an important factor in determining the structural stability, which was done by ANSYS program and experimental investigation was carried out on many specimens of composite material of E-glass fiber reinforced polyester plastic materials with different no. of layers. Five cases are studied to show the effect of cutout’s parameter on the structural stability in which the shape ( circle, square, rectangle), size (20, 30, 50 ) mm, rounding corner (5, 7.5, 10)mm and orientation of cutouts (0°,30°,45°,60°) are presented . Also the effect of plate thickness (no. of layer) is studied . In general , the results of the square clamped laminated plates with circle cutout come out in a good agreement. Which is decrease of buckling load of the plates with change the shape from circle, square and rectangle and in case of cutout size. The critical load is still constant with the radii rounding corner and increased with increasing the cutout orientation and the thickness of the plate. The effect of cutout will determine the increase or decrease of the buckling | ||
