Abstract

The dynamic response of steel beams treated with various configurations of constrained viscoelastic layers is considered experimentally and analytically. The cantilevered sandwich beams are subjected to spike inputs and large finite rotations. Frequency domain viscoelastic material properties provided by the manufacturer are converted to the Prony series time domain expression of the shear relaxation modulus. A finite element model of the cantilevered beams is implemented in ABAQUS and numerical predictions are obtained. Natural frequencies and damping factors obtained from linear and nonlinear, time domain finite element analyses are found to be in good agreement with experimental results.
