Frequency response of the cantilever Timoshenko beam subjected to large displacements, showing displacement amplitudes for different excitation force levels (Readings are taken from the free tip and units in rad/s for frequency and m for displacement).
Fig 6.
Frequency response of the bar with frictional clamps for different levels of imposed strain (Readings are taken at the contact point of the beam and the clamps and units are nondimensionalised for frequency by dividing the frequency axis by the reference value of the first axial mode of a clamped-clamped beam and displacement by dividing the displacement amplitude values by the displacement amplitude imposed on the clamps).
