Buckling Analysis of Symmetrically Laminated Composite Plates

대칭복합적층평판의 좌굴해석

The experimental and numerical results of buckling loads for symmetrically laminated composite plates are compared. Boundary conditions are all fixed supports. Experiments were conducted for plates with fiber angles $\theta$=30$^{\circ}$, 45$^{\circ}$, 60$^{\circ}$ and aspect ratios a/b=0.8. Experimental results were obtained from load-deflection curves. Numerical methods were presented to evaluate buckling loads, using structural analysis results from ANSYS.
