Experimental and Numerical Study on Vibration and Buckling Characteristics of Laminated Composite Plates

摘要: Composite materials are being increasingly used in automotive, civil, marine, and especially weight sensitive aerospace application, primarily because of its specific strength stiffness. The present research is mostly experimental study based on vibration measurement buckling behavior industry driven woven fiber composite panels. effects different geometry, boundary conditions, aspect ratio type hygrothermal conditions the natural frequencies panels studied this investigation. Experiments have also been conducted to characteristics carbon/glass hybrid plates for lamination sequence percentage carbon glass fiber. finite element package, ANSYS 13.0 was obtain numerical results validate obtained. free with FFT analyzer. critical load determined using INSTRON 1195.
