Energy partitioning in elasto-plastic impact by sharp abrasive particles in the abrasive water jet machining of brittle materials

摘要

In the abrasive water jet machining (AWJM) of brittle materials, the stress wave energy, associatedwith the impact of abrasive particles, plays an important factor in material removal by fracture. Themodels currently available are idealised and simplified and cannot take into account the particle shapeor size. The present paper addresses the problem of taking into consideration the size and shape of theparticles. The results indicate that use of spherical blunt particles in the AWJM of brittle materials willlead to more fracture.
