TRANSVERSE FREE-VIBRATIONS OF RIGHT TRIANGULAR THIN PLATES WITH COMBINATIONS OF CLAMPED AND SIMPLY SUPPORTED BOUNDARY-CONDITIONS - A HIGHLY ACCURATE SIMPLIFIED SOLUTION

The practical engineering problem of right angled triangular plates with combinations of clamped and simply supported boundary conditions is dealt with in this paper. A highly accurate, economical and practical solution is used for the transverse free vibration analysis of these plates. The solution is based on a modified superposition method. The accuracy of the solution is discussed. Numerical results are compared with previously published reliable data. The advantages of the solution used in the paper over previously published solutions are discussed. Eigenvalues, mode shapes and contour plots are provided for a large number of plates.
