Free vibrations of a partially clamped trapezoidal plate

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.

Finite element linear and nonlinear, static and dynamic analysis of structural elements: a bibliography (1992‐1995)

Abstract: Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.

Experimental and numerical investigations for the free vibration of cantilever trapezoidal plates

Abstract: Based on the advantages of non‐contact and full field measurement, the optical technique called amplitude‐fluctuation electronic speckle pattern interferometry (AFESPI) with an out‐of‐plane setup is employed to investigate the free vibration of cantilever trapezoidal plates with various taper ratios and sweep‐back angles. Twenty different plate configurations are analyzed, including triangular and trapezoidal plates, and the first seven vibration modes of each plate are measured. The AF‐ESPI method is very convenient for measuring vibrating objects because no contact is required in contrast to classical modal analysis using accelerometers. Based on the fact that clear fringe patterns will appear only in resonance, both resonant frequencies and corresponding mode shapes can be obtained experimentally using the present technique. Numerical calculations by finite element method are also performed and the results are compared with the experimental measurements. Excellent agreements are obtained for b...

Free vibration investigations for the cantilever-symmetric and skew-symmetric trapezoidal plates with cracks

Abstract: Using the advantages of non-contact and full-field measurements, the optical technique called amplitude-fluctuation electronic speckle pattern interferometry (AF-ESPI) with out-of-plane setup is employed to investigate the free vibration of cantilever-symmetric and skew-symmetric trapezoidal plates with cracks. Three different types of crack locations will be discussed in detail in this study, one is along the middle chord line and the others are along the clamped edge. Prior to the study of cracked trapezoidal plates, a cantilever rectangular plate is used to carry out the AF-ESPI measurement, and then the experimental results are checked by theoretical and numerical calculations. Numerical calculations based on the finite element method are performed and compared with the experimental results, in which good agreement is obtained for resonant frequencies and mode shapes. Finally, the influences of crack length and location on the vibration behavior of the cracked trapezoidal plates are studied in terms o...
