Abstract

A power dissipation capability for solid elements is developed and validated against experimental and beam model data. For most frequencies the solid model predicts experimental power dissipations better than the beam model. However, the solid model data do not agree well with experimental data at frequencies between 900 and 950 Hz. The reason for the disagreement is a weakly excited mode at 944 Hz. The mode is active in the actual T-beam and the beam model, but inactive in the solid model. In general though, the data for both finite element models matches experimental measurements very well.
