A NEW BOUNDARY SPECTRAL STRIP METHOD FOR NON-PERIODICAL GEOMETRICAL ENTITIES BASED ON ANALYTICAL INTEGRATIONS

A method based on expanding the boundary integral equation into a trig onometric series or a high-order polynom is proposed, depending on the domain geometry. It is a non-element method which yields solutions to elastostatic and potential problems, using a small computer memory, y et obtaining more precise results as compared with other common numeri cal methods. When the geometry of the problem contains circles and str aight lines, all the integrations required for solution of the boundar y integral are solved analytically. Some elastostatic problems are sol ved here, and compared with the boundary element method (BEM), which s hows some remarkable advantages of the boundary strip method over the BEM.
