Buckling analysis of laminated composite panels

In this study, the numeric buckling analysis for the dimensions and different orientation angles and different hole geometry on the symmetric and anti-symmetric layer rang of fiber, graphite fiber and carbon/graphite fiber produced from the cross reinforced polyester are realized . In modeling and analysis ANSYS 11.0 elements packet program has been used. The results realized as a result of the analysis have been compared and presented as graphics. When taking the layer range into consideration, it is found out that the composite plates which have symmetric layer range have much lower buckling load than the anti-symmetric layer range platesKey Words: Hybrid composite, delamination, orientation angle, buckling, ANSYS.
