A method for conducting finite element analysis of a component which takes into consideration the apparent rigidity of an interface structure. The method generally includes the steps of (a) providing a standard shim bar, (b) physically measuring the natural frequencies of the standard shim bar when mounted to the interface structure, (c) generating a finite element model having a shim interposed between the component and ground, (d) selecting the characteristics of the shim as a function of the measured natural frequencies of the standard test bar, and (e) once the appropriate characteristics are selected, performing the desired finite element analysis on the finite element model. |
