In the present research, vibration and instability of axially moving
sandwich plate made of soft core and composite face sheets under initial
tension is investigated. Single-walled carbon nano-tubes (SWCNTs) are selected
as a reinforcement of composite face sheets inside Poly methyl methacrylate
(PMMA) matrix. Higher order shear deformation theory (HSDT) is utilized due to
its accuracy of polynomial functions than other plate theories. Based on
extended rule of mixture, the structural properties of composite face sheets
are taken into consideration. Motion equations are obtained by means of
Hamilton’s principle and solved analytically. Influences of various parameters
such as axially moving speed, volume fraction of CNTs, pre-tension, thickness
and aspect ratio of sandwich plate on the vibration characteristics of moving
system are discussed in details. The results indicated that the critical speed
of moving sandwich plate is strongly dependent on the volume fraction of CNTs.
Therefore, the critical speed of moving sandwich plate can be improved by
adding appropriate values of CNTs. The results of this investigation can be
used in design and manufacturing of marine vessels and aircrafts.
