Flutter of cantilevered plates in axial flow

WebAug 28, 2014 · As for the cantilevered plates free at their trailing ends, the large-deformation nonlinearity generally leads plates to undergo the limit cycle oscillations (LCOs and hereafter) after flutter instability. Tang et al. examined the flutter instability and LCOs of a cantilevered plate in axial flow. The structural nonlinearity model was derived ... WebFeb 1, 2003 · Experimental flutter and limit cycle oscillations (LCO) of two-dimensional elastic plates in three-dimensional axial flow were observed. The plate is clamped at its leading edge and free at its trailing edge, i.e., it is a “flag” albeit one dominated by its bending stiffness.
