Ultrasonic assisted machining (UAM) is an efficient nontraditional machining operation for brittle, hard-to-cut and poor-machinability materials.
Most of the above ultrasonic setups are designed for a special condition (certain geometry and workpeice) and are not efficient when workpeice material or dimensions are changed.

Introduction
Steel bonded carbide is a kind of composite materials which the steel as binder phase, refractory metal carbides (titanium carbide, tungsten carbide) as hard phase.
The infiltration casting method is used for many times in development and application of composite materials for the steel substrate preparation more [9].

Study on Bonding Properties of Copper and Aluminum in Nano Scale Using Molecular Dynamics Simulation
Online since: January 2012
Authors: Quang Cherng Hsu, Yen Yu Cheng, Bao Hsin Liu
MD has been widely used to simulate the material behaviors in a variety of materials in nano scale movement.
It was found that the ultimate tensile strain for BCC materials is smaller than FCC materials and the ultimate tensile stress for rapid stretching is larger than slow stretching.
Also, Morse potential was concluded less suitable for analyzing the materials with BCC.

Ductile fracture criterion and material constants
The material used in this study is sheet metal 2A12-0 with a thickness of 1.5 mm.
The simulations are base on the Hill's yield criterion which is suitable for normal anisotropy materials.
Materials perform a better plasticity under compressive stress state proved by many experiments, that's why the micro holes group up slowly with the smaller degree of stress triaxiality ( h / ), vice versa [9].
