Abstract
The natural frequencies and mode shapes of partially clamped trapezoidal cantilever plates having various swept-back angles are examined numerically and experimentally by a finite-element computer program, SAP6, and holographic interferometry, respectively. A good agreement is found between the numerical and the experimental results. The influence of the clamped position, the free-width ratio, and the swept-back angle on the vibratory behavior of the trapezoidal plates is investigated.
