The Library of Compliant Mechanisms has been organized to present compliant elements and designs in a simple and intuitive manner. The organization of the library is described. The classification scheme incorporates similar classification techniques used to categorize traditional rigid-body mechanisms, and classifies mechanisms according to their function, and includes the mechanism depiction and a concise description of its behavior. The purpose of the categorization is to show the reader how the library has been organized to efficiently access particular entries, or find entries that achieve particular functions. Two systems of categorizing compliant mechanisms were determined to be convenient for engineers: categorizing according to Elements of Mechanisms and Mechanisms.
