The principal objective of MM2003 was to create an international forum for the exchange, dissemination and discussion of the state-of-the-art technologies and recent developments in macro-, meso-, micro-, nano-mechanics of materials and structures.
While MM2003 focused on the most recent advances in strength, fracture and mechanics of micro- and nano-structured materials, it also served to link the gaps between the conventional macro/mesosystems and the emerging micro/nano-materials technology. 128 papers were presented at MM2003, covering the following areas: Nanotube/Nanofiber; Thin films; Biomaterials & Biomimetics; Polymer/Composites/Interface; Fatigue & Creep; Piezoelectrics & Ferroelectrics; Fracture Mechanics; Fracture Physics; Computational Mechanics; Mechanics of Rock & Concrete; Dynamic Fracture & Damage.
Amongst these topical areas, papers in the fields of composite materials; thin films and coatings; as well as fracture, fatigue and strengths of advanced materials are included here.

With the development of cutting theories and materials of cutting tool, high speed cutting is considered as a fast developing and comprehensive engineering technology with great potential and was applied widely in many industrial field such as aeronautics and astronautics, automobile, mould, etc.
Thus when cutting tool advances into workpiece with a very high speed, the temperature in workpiece surface would be very high in a short time, and the machined surface suffers a heat change.
