Abstract:The theory and application of SPH (Smoothed Particle Hydrodynamics) is presented. A Langrangian SPH model is conducted using the LS-DYNA software. As a recently developed and promising method, particles are used in SPH as a substitute for mesh and large material deformation is easily handled. Material separation is well achieved through defining nodes to surface contact. The cutting process of 4340 steel is simulated with SPH method. The process of chip formation is depicted well through the natural flow of SPH particles. The stress distribution and changes of cutting force displays the constitutive behavior of material during cutting. And the maximum value of Von Mises stress, shear stress and plastic strain are concentrated at primary deformation zone, especially near the tool tip.
