Published Online: January 5, 2023
Fig. 2 Discontinuous rise in flutter Mach number as a concentrated mass ratio η is varied for s η = 0.9 (solid line). If the mass ratio was instead increased in a homogeneous fashion (increasing thickness, dashed line), an abrupt flutter mode switch does not occur. More

Fig. 3 Eigenvalue behavior two different concentrated mass ratios: one prior to the discontinuous jump in flutter Mach number (a,b; η = 0.2), and one after (c,d; η = 0.3). For both cases, s η = 0.9 . More

Fig. 4 Flutter Mach number behavior as a mass ( η = 0.5) is varied along the length of the plate. From left to right in ( a ), we see in ( b ) that traditional modes 1 and 2 merging drives flutter. At about s η = 0.35 flutter is due to merging of modes 2 and 3 ( c ). Between the dash... More
