This paper will discuss the combination of experimental and analytical representations of components into a complex non-conservative system model where the goal is to predict the load field on the various components due to known inputs to the system. Static correction terms are used to improve the modal representation of components by accounting for the effect of truncated higher frequency modes. As will be demonstrated, loads, stresses, and strains as experienced by individual components can be determined with a high degree of confidence. These strain time histories can then be used for fatigue life predictions of the components. This process will be illustrated with an example involving durability studies of a military vehicle design.
