Dynamic-stiffness matrix of unbounded soil by finite-element multi-cell cloning |
|
| Authors: | John P Wolf Chongmin Song |
| Abstract: | To calculate the dynamic-stiffness matrix of the unbounded soil, a multi-cell cloning algorithm based solely on the finite-element formulation is developed. A non-linear system of equations has to be solved iteratively once for the whole range of frequency. For a specific frequency, two- and three-cell cloning lead to highly accurate results, which is demonstrated by examples of increasing complexity. |
