A method and device for controlling strain and deflection in a superstructure, resulting from movement/displacement of the main structure on maritime and aerospace vessels, and other structures which have significant strains and/or deflections induced by support displacements. This method involves the use of elastic devices inserted in the said superstructure and fine tuned with respect to stiffness, to an extent where the load distribution throughout the said superstructure can be controlled. The device is constructed by the use of material formed in a geometric shape which will allow yielding, to a desired amount of strain and/or deflections, in the elastic device, superstructure and main structure.
A stiffness tuned structural load carrying elastic device for use in and between spaced sections of a superstructure of a ship said device, consisting of joining sections, each formed with an offset discontinuity which are attached between sections of a superstructure of a ship which will allow a predetermined amount of strain and deflection and load between said sections of aid superstructure and will limit the initiation of new cracks and the propagation of existing cracks and flaws in the said superstructure.
