Scope of the Conference
This will be the fifth International Conference in the series organised by the European Structural Integrity Society - Technical Committee 4 on Fracture Mechanics related to Polymers, Polymeric Composites and Adhesives. We are inviting papers in the areas reflecting the current and future interests of TC4 as listed below. New developments and innovative applications are especially welcome. Both experimental and analytical work is sought in order to give a balanced view of the subject areas:

Polymers
Low rate properties, Kc, Gc and Jc. Essential work of fracture, we. Impact and high rate properties. Ductile energy dissipation. Environmental effects. Fracture in soft materials. Cutting, machining and scratching. 

Composites
Delamination in continuous fibre composites including cross-ply, z-pinned and stitched laminates. Impact and high rate properties. Fatigue and thermal properties. Toughness of short fibre and particulate composites. Nano composites and the ‘Nano effect.’

Adhesives
Structural adhesives toughness evaluation. Geometry and thickness effects on Gc. Toughening mechanisms, including nano-scale additives. Service life prediction models, including cyclic fatigue loads and environmental ageing effects. Impact and high rate behaviour. Peeling of flexible laminates.

Application of fracture mechanics
Data for FE design codes. Applications in electronics, pipelines and layered structures. Crash simulations.

2007 Dynamic Compression of Condensed Matter
5 - 6 December 2007
The Royal Society, London

The physical science behind dynamic response holds key challenges.

There is a need to understand materials under the extreme environments encountered in energy generation, conversion and exploitation and in wider industrial and defence applications. This meeting will bring together the community to focus on potentially significant emerging and scientifically challenging areas. It will span research areas informing the dynamic response of materials, new techniques and emerging diagnostics, and their application to the atomic to planetary scale. Keynote invited lecturers will outline the state of their fields of interest. The meeting format will encourage debate to air technical experience and identify future challenges ending with a round table discussion defining the key aspects of the field for the next decade.

Conference Overview

• Shock physics in the 21st century
• High pressure physics
• Response under dynamic loading
• Strength and damage
• Equations of state
• Detonation physics
• Isentropic loading
• Applications in planetary and space science
• Materials at multiple length- and time-scales
