To predict the critical flutter load and frequencies of doubly curved panels using first-order shear deformation theory considering the effects of shear deformation and rotary inertia.Design/methodology/approach – A finite element analysis procedure is based on the extension of dynamic, shear deformable theory initially according to Sanders' theory, which can be reduced to Love's and Donnell's theories by means of tracers.Findings – Flutter is observed to be more common than divergence under follower loading; the magnitude of the flutter load is gradually decreasing with the increasing cut-out size; load bandwidth and type of load conditions have significant influence on flutter and divergence characteristics of both isotropic and laminated curved panels; damping is perceived to have significant effect on flutter behaviour; the effect of direction control parameter with damping significantly affects the critical load.Practical implications – The practical behaviour of follower forces involving: aerodynamic drag; engine thrust; cantilever pipe conveying fluid; gas turbine rotor; automatic control system application; and automobile disk brakes can be monitored more successfully.Originality/value – Will assist students of elastic systems, both conservative and non-conservative.
