... that the work of adhesion can be done by applying a large force over a small distance (uniform tension) or a small force over a large distance (as in peeling or sliding). In a similar way, the fracture threshold also depends on the mode of separation, such as tension versus shear. Therefore, an adhesion test...

... and some erosion processes can involve dissolution. Adhesive wear is fracture produced by solid-state bonding of one material to another. If motion persists after bonding, fracture must take place. Material “A” may fracture, with some of it bonding to contacting material “B,” or the fractured material...

For example, a wear coating on a soft substrate will not function well if, under load, it is fractured by the deformation of the underlying substrate. Also, good film adhesion cannot be obtained when the substrate surface is mechanically weak, because failure can...
