Abstract
Provided are assemblies, comprising: a first leaf spring; a second leaf spring; and at least one component; the first leaf spring and the second leaf spring being superposed over a first end of the at least one component so as to exert first and second forces, respectively, through first and second regions of the component. These assemblies are useful to apply different forces to a stacked assembly where a cross section of a component of the assembly comprises materials of different Young's moduli within that cross section, thereby compressing different regions of the component with different forces.
Claims19
A method, comprising:
- securing a first leaf spring and a second leaf spring superposed over one another such that
- a. the first leaf spring exerts a first force in an axial direction into a first region of a cross-section of one or more components, the first region extending axially and defining a first Young's modulus,
- b. the second leaf spring exerts a second force in an axial direction into a second region of the cross-section of the one or more components, the second region extending axially and defining a second Young's modulus,
- wherein the securing is with one or more tie rods, the first force differing from the second force in magnitude, and
- the first Young's modulus differing from the second Young's modulus.
