| Abstract: |
| The present paper suggests a new expansion method of random fields on the Galerkin Projective Method. A set of standard independent bases is constructed, then the random field is expanded with its projection on the bases. This method avoids the difficulty in solving the integral eigenvalue problem. Further, the error with the present method is discussed. Finally, the numerical examples illustrate the features of the new method. |
