Introduction Crack propagation simulation is an important topic in many fields, for example, aeronautical engineering, material science, and geophysics.
The mechanical behavior of macro scale structure of metals materials depends strongly on evolution of the micro structure. n this paper, use a molecular MD and FE approach to study the evolution and propagation of cracks and fractures in Al materials The goals of this study are to establish the mechanical properties of cracks and fractures and to ascertain the evolvement mechanism of crack tip based on the results of simulation.
Computational Model Pure aluminum single crystal material was selected as research object, and this Al material by the far field stress is shown in Fig.1.A small area near the crack tip in the material was calculated by the molecular dynamics.

The cutting tool material is K cemented carbide, and the work piece material is Ti6Al4V.
The simulation material constitutive model adopts the build-in material constitutive model, i.e. the power-law model.
Therefore, in the finite element simulation process, 45 steel's material models should use the Johnson-Cook material model.

The conference was an action of the International Federation for the Promotion of Mechanism and Machine Science (IFToMM).
Two mini-symposia oriented to problems of Non-linear Dynamics have been organized: (i) MS01 - Non-linear Dynamics and Dynamic Stability, organized by Jiří Náprstek (Czech Republic), (ii) MS07 - Nonlinear Dynamic Interactions and Phenomena: Emergent Methods and their Applications in Engineering and Science, organized by Jose-Manoel Balthazar and Paulo Batista Goncalves (Brazil) The scope of both mini-symposia was broad.
Organizers of MS01 and MS07 invited authors of all presented papers after the conference to submit modified and extended versions to the special issue of the journal Applied Mechanics and Materials.

Brazing is a materials-joining technology that applies heat to the base metals and brings the filler metal into contact with the heated parts.
This material has good high temperature properties and good erosion resistance.
