Particle Methods to Model Ductile, Heat Conductive Material

摘要

This contribution presents a method to model separable, ductile and heat conductive material using the Discrete Element Method for the multi-body simulation. The model is based on a conventional three-dimensional discrete element model which employs rigid spheres. Cohesion is achieved by defining appropriate force laws whose behavior is controlled by several parameters which allows a natural and simple inclusion of separation of the material. Temperature is defined as an extended state for each particle which is used as input for a temperature interaction, i.e. heat flux. The applicability of the method is demonstrated in a cutting process for modern machine tools.
