ABSTRACT:
A resilient material element with graded stiffnesses is disclosed comprising radial substructures carried by the body of the element and separated by radial gaps, these substructures themselves carrying studs of more reduced cross section. When the element is subjected to compression forces in the axial direction, the studs are crushed, then the substructures, which confers on the element sudden increases of stiffness. An additional increase of stiffness is provided when, with the substructures expanded laterally, their facing walls come into mutual abutment, which completely closes the gaps.
