Abstract This study investigates the static instability of a cracked plate in subsonic airflow. The plate model is an
inverted cantilever plate, where its leading edge is free and the trailing edge the clamped. A mathematical
model of the crack is developed using the Dirac function, while Theodorsen aerodynamic mode is applied
for the fluid force. To account for angle discontinuity caused by cracks, Fourier expansion is employed to
transform the form corresponding to the angle into a continuous model. The critical divergent dynamic
pressure and mode of an inverted cantilever plate with a crack are More >
