The physics of particle adhesion is a complex subject and depends on the interaction mechanisms and the mechanical properties of the contacting materials. These interactions, which tend to be caused by van der Waals and electrostatic interactions, generate stresses that, in turn, result in deformations of the contacting materials. Most of today's understanding of particle adhesion is based on theories...
In bound-abrasive grinding, the abrasive particles are subjected to normal and frictional forces due to their interactions with the workpiece. These forces generate stresses at the abrasive particle-matrix interface (also referred to as the interface in the following text). Debonding, or fallout of abrasive particles, will be affected by the stress state at the interface, which is determined by...
In this experimental investigation, the effects of fracture surface interface upon the torsional properties of steel alloys were quantitatively characterized. A cyclic compression pre-cracking technique was employed to produce microscopically fine crack fronts in circumferentially notched cylindrical test specimens. The abrasion and deformation that the resulting fracture surfaces underwent during...
