Vibration analysis of functionally graded material (FGM) grid systems
Kutlu Darılmaz

 
Abstract
    The paper considers the free vibration analysis of FGM grid systems. Up to now, very little work has been done on this type of system and the paper aspires to fill this gap. Based on the hybrid-stress finite element formulation free vibration solutions for FGM grid systems of various aspect ratios, different types of gradations functions, and support conditions are determined. The tabulation of these results, not available thus far, should be useful to designers and researchers who may use them.
 
Key Words
    grid system; functionally graded materials; free vibration; hybrid finite element
