The purpose of this session is to foster the interaction and networking of those working throughout universities, industries, and government laboratories in the general area of micro and nano systems, and to provide an opportunity for the exchange of ideas in an interdisciplinary forum.

The field of nano science and technology is a broad and interdisciplinary area. Worldwide research and development activities have been growing rapidly in the past few years, while an understanding of the range and nature of functionalities that can be accessed through nanostructuring is just beginning to unfold.

The understanding and prevention of fracture and fatigue in micro and nano engineering applications depends upon the integration of knowledge in materials science, physics, chemistry and mechanics. Our progress may fundamentally change the way in which materials and devices will be produced in the future, and revolutionize segments of the materials manufacturing industry.

This session will focus on fracture and fatigue at the nanoscale within the larger scope of assessing research needs in a variety of applications of interest.

Topics of particular interest include, but are not limited to, the following areas:

• Fatigue and Fracture in MEMS/NEMS.
• Novel test techniques from nanometer to micrometer length scales.
• Deformation and fracture of biomolecules
• Mechanisms of surface and thin film coarsening; self-organized pattern formation in thin films, driven atomic motion.
• Adhesion, fracture and plasticity of thin films and coatings.
• Modeling mechanical behavior of nanostructured materials; defect structure and interface structure of nanocomposites.
• In-situ AFM/SEM/HRTEM experiments performed on thin films and nano tubes.
• Collective dynamics of defects and interplay between phase composition, phase transformations, and plasticity.
• Simulation methods for length scale linking; coupling quantum to atomistic and atomistic to continuum simulations.

The basic words of the technical economical life are: Safety, Reliability and Risk. General tendency of the activities in the field of real economical life to find the more and more cost effective solutions for the life cycle engineering which includes the design, operation and recycling technologies. The tools are involved into the mentioned periods of the product life are developing very quickly that is why the risk of different solutions can be estimated better and better. This situation provide to implement the risk based approaches in different field among them in the operating periods of the engineering productions, structures. This process has been accelerated in Europe by the results of different European projects financed by the Framework Programs. The main results, applications will be presented in this session including the refineries, chemical plants, power plants.

The emergence of novel functional nanocomponents such as nanotubes, nanobelts, nanodisks, nanowires, nanocoils, and nanocoatings and nanostructured materials such as nanocrystals and nanocomposites has excited active research at the nanoscale. Computational analyses using atomistic and continuum approaches have been increasingly used along with synthesis and experimental analyses. One trend is the convergence of physics, mechanics and materials science. This symposium is intended to bring together researchers from the mechanics, physics, and materials communities with a focus on offering a glimpse at some of the state-of-the-art research on the mechanical and thermal behaviors of materials at the nanoscale. Topics to be covered include:

• Atomistic & continuum modeling of nanoscale deformation & failure
• Mechanical & thermal behaviors of nanocomponents & nanostructured materials
• Experimental characterization of nanoscale deformation, fracture & fatigue
• Nanoindentation
• Superelasticity & plasticity of nanowires, nanobelts, & nanotubes
• Size effect at the nanoscale
• Deformation & failure of nanocomposites & nanostructured materials
• Effects of synthesis & fabrication on nanoscale behavior

Please send abstracts to Dr. Min Zhou through email at min.zhou@me.gatech.edu by March 31, 2005.

Fracture and Fatigue of Elastomers

Organizer: Professor Claude Bathias and
Emin Bayraktar, Associate Professor
Conservatoire National des Arts et Métiers
ITMA, 2, rue Conte, Paris 75003, France
Tel, Fax : 33 140272322,
Email : bathias@cnam.fr

This symposium is devoted to the mechanical behaviour of elastomers including static fracture and fatigue damage of naturals and synthetic rubbers. The aim of this event is supported by the European industry of rubber, suppliers, consumers and technical centres, in order to increase the reliability of components, parts and tires, reliability which is more and more important facing safety and durability versus the cost.
Since the development of this industrial sector is growing fast, the number of European academic laboratories involved in this field is certainly insufficient. According this situation, the following topics of particular interest are opened for presentation:

-Modelling of mechanicals behaviour
-Monotonic fracture
-Application of fracture mechanics
-Criteria of fracture
-Effect of crystallization on the strength
-Effect of environment
-Effect of hydrostatic pressure
-Initiation of fatigue cracks
-Bi axial fatigue
-Fracture analyse
-Non destructive testing

Abstracts and in formations should be submitted to the above email: bathias@cnam.fr
