Twelve moving parts per side, oscillating undulation, weight distributing, cushioning conforms to your horse and saddle restoring proper motion by reduction of stress and trauma to back, shoulders, and loin, offering breathability and moisture flow for less heat build up. The Mechanics of Ultimate Performance Pads Adhesion vs. Stress Adhesion is the force applied to the materials together. In specific adhesion, its the molecular attraction between contracting surfaces. Mechanical adhesion occures when applies to rough or porous surfaces. Effective adhesion combines specific and mechanical to form optimum strength vs. stress.
Stress is the force applied to the materials through four basic types.
Tensile is exerted equally over the entire surface in a pull direction bonding is for optimum strength. Cleavage is force concentrated at one edge and exerts a prying force. The other edge is now under zero stress. Peel is concentrated along a thin line at the edge. Bonding has a flexible surface to stay out in front of the mating surface.
