On the stiffness characteristics of nonmonolithic elastic structures. Part II. Applications and examples

The theoretical results of Part I [Int. J. Solids Struct. 39, 1673–1699] have been applied to beam and arch structures using a procedure where the nonmonolithic structure is decomposed into an elastic monolithic structure and a rigid body assemblage with partial interpenetration at the joints. Furthermore the indentation of an elastic strip by a rigid punch with various profiles has been analysed by approximate methods. Using the extremum principles concerning the stiffness and the extent of contact, upper and lower bounds of the stiffness characteristics have been determined
