Abstract

Sub-modeling techniques implemented in commercial finite element codes were reviewed. New sub-modeling applications in structural mechanics stress analysis are presented. Sub-modeling methods based on displacement and force cut boundary application are compared. Advantages and disadvantages of these methods are discussed. The case of nested sub-models is demonstrated.
