Description of Model:

Determine the frequency response of a 5x2 inch flat plate under frequency-varying excitation by using a direct formulation. A unit load at the place corner will excite the plate model. A frequency step of 20Hz will be used for this analysis within the range of 20 and 100Hz.

Structural dumping will be set to 0.06.
