Structures subject to bending and fatigue loading

摘要

A structure to be subjected to bending and fatigue loading comprises two components having different stiffness connected together. Deflection of the more flexible component is accommodated by the interposition of an intermediate member of varying flexibility between the components or by providing the less flexible component with a flexible portion to act as a fulcrum for the deflection. The components may be a radar-transparent cover and a mounting therefor for use in a submarine.
