Abstract: Abstract The condensation technique for the deletion of unwanted degrees of freedom was first proposed by Guyan (1965) and Irons (1965) in 1965. Because the dynamic effect is ignored in the condensation, this method is usually referred to as static condensation. Since the late 1960s, this technique has been widely used in many static and dynamic problems. Several examples of the applications are the component mode synthesis, eigenproblem analysis of large models, and experimental mode expansion. This approach has been included in many textbooks in the areas of structural dynamics and mechanical vibrations (Weaver and Johnston, 1987; Argyris and Mlejnek, 1991; Petyt, 1990; Bathe, 1996). Today, it is still one of the most popular condensation methods.
