Abstract

Abstract: It is evident that substantial work has been done to understand the free vibration response of solid composite laminated plates with cutout for different combinations of parameters that affect the dynamic characteristics of plates. In case of square plates with square or rectangular cutouts, a complete picture on dynamic characteristics for different layup sequences and different boundary conditions are not available. Again the difference in dynamic behavior of laminated composite plates with cut-out for various thicknesses are not covered previously. The objective of the present investigation is to understand the effect of the rectangular and square shaped cutout on the free vibration response of laminated composite plate based on different boundary conditions, layup sequences and thickness.Keywords: Classical Lamination Theory(CLT),First Order Shear deformation theory(FSDT),High Order Shear Deformation Theory(HSDT),Layer Wise Lamination theory(LLT)
