.... In case if you are not aware of the amount of scatter, then a maximum of 10% coefficient of variation can be chosen as per the Federal Aviation Administration (FAA) regulations for composite materials. Hence, in our study, we have limited the COV of material properties with in this range. Figure 3 shows...

... at frequencies near the first bending mode. Kim and Han ( 8 ) designed and fabricated a smart flapping wing by using a graphite/epoxy composite material and a MFC actuator. This paper was aimed to mimic the flapping motion of birds. A 20% increase in the lift was achieved in wind tunnel by changing...

.... This phenomenon was not discussed in the previous related studies; and the discussions in the related studies are found applicable for frequencies below the cutoff frequency. It was recognized that due to anisotropy of composite materials, the application of either a bending or twisting moment by itself...
