Natural vibrations of cantilevered triangular plates i
(
Book
)
1 edition published in 1952 in English and held by 1 WorldCat member library worldwide
In this report the Rayleigh and RayleighRitz methods are applied to the natural vibrations of uniform triangular plates clamped on one edge and free on the other two. Two shapes of plate are investigated: an isosceles plate clamped on the base and a right triangular plate clamped on one leg. Upper bounds are obtained for the fundamental modes and in some cases for the second and third modes as well. The following classes of functions are used to represent the displacement of the plate: (1) Oneparameter polynomials with integral exponents; (2) Twoparameter polynomials with integral exponents; (3) Threeparameter polynomials with integral exponents; (4) Fiveparameter polynomials with integral exponents; and (5) Monomials and binomials with variable exponents. In the absence of an exact solution of the problem the frequencies obtained are compared with experimentally determined frequencies for plates of similar shape. For this purpose a formula is developed which relates the frequencies of plates of similar planform but differing in size, thickness, and materials. The comparison between the analytical and experimental results is summarized in a table. While several of the simpler functions yield a satisfactory approximation to the fundamental frequency, only the fiveparameter function (of the functions thus far examined) gives reasonable accuracy in the second and third modes, and at the same time it offers a good approximation to the fundamental.

(
Book
)
1 edition published in 1971 in English and held by 1 WorldCat member library worldwide
This is a record of a research project in applied mathematics at CarnegieMellon University. The project is called 'Analysis of Electrical and Mechanical Systems' or AEMS for short. The aims of AEMS are threefold: (a) to apply mathematical analysis to treat new problems arising in science and technology; (b) to develop new mathematical concepts and structures using facets of science and technology as models; and (c) to help students start a career in the interesting area of applied mathematics.
