BALL INCORPORATING ELEMENT FOR CRACKING COVER

摘要

A ball includes a core, a cover, and cracking element or cracking layer. The cracking layer may be deformed or actuated to create discontinuities in the cover. The creation of discontinuities allows for easier recycling of the ball parts. The cracking layer may include one of a bladder or a hydrophilic material that expand upon the introduction of a fluid, a shape memory polymer that deforms upon application of a stimulus, or two materials that react chemically to form a gas.
