Modelling and Simulation of Cutting Process by Smoothed Particle Hydrodynamics (SPH): A Review

Smoothed Particle Hydrodynamics (SPH) is a meshfree (particle) method that was firstly proposed for astrophysics application. Nowadays, after the efforts in last two decades, it has been gradually extended to the research of cutting process. This review paper aims at presenting a comprehensive review of the modelling and simulation of cutting process using SPH method. It introduces the basic theory of SPH and its adoption for cutting process simulation. The key focus of the paper is on the gain of understanding of cutting mechanism by the aid of SPH method. Research challenges and recommendations for future works are also summarized.
