AN INVESTIGATION ON A NEW INTEGRAL TRANSFORM—BOUNDARY ELEMENT METHOD FOR ELASTODYNAMICS

摘要

The numerical methods of Fourier eigen transform FET and its inversion are discussed and applied to the boundary element method for elastodynamics. The program for solving elastody-namic problems with the boundary element method is developed and some examples are given. From the numerical results of the examples, we know the method can increase the computing speed 5～10 times and the accuracy is guaranteed.
