FINITE ELEMENT MODEL

Finite element modeling has been widely used for several decades now. The finite element process is widely used in a wide range of industries to assist in the design process. There are many textbooks on the modeling process. Generic information of the process is not discussed herein.

However, there are many aspects of the development of the model that are of concern when using a model for correlation with measured data. The development of the model is always troubled by the modeling of joints, interconnection of components and the lack of damping in the model, to name a few widely recognized concerns. Other concerns include the types of boundary conditions, use of special rigid elements and use of lumped masses which can have a significant impact on the success of the correlation process.
