Technical Committee: TC3, Fatigue of engineering materials and structures

Fracture failure (any failure caused by crack propagation under static loading) and fatigue failure (gradual crack propagation under time-varying loading) are among the most catastrophic failures that structural components and structures may experience, since they occur without any warning.

An accurate estimation where crack is nucleated inside the material and when failure is expected to occur are ancient problems in the design of structural components and structures.

The purpose of this Symposium is to collect presentations aimed at providing an up-to-date overview of several topics in the research field of both fracture and fatigue. Engineers, metallurgists, material scientists are encouraged to submit their research focused on theoretical or experimental aspects, as well as on engineering case studies and examples.

Technical Committee: TC4, Polymers, Polymer Composites and Adhesives

The session aims at current aspects of fracture of polymer-based materials and of joints, components, and structures made with them. Besides all scales from nano to macroscopic size also the full range of loading-rates and of variable environmental exposure are of in-terest. This is complemented by developments in experimental test methods, characteri-zation techniques and analysis as well as numerical and modelling approaches. Of special interest are novel polymer-based materials and composites, e.g., renewable or biode-gradable polymer composites or materials and parts made with new processing and manufacturing technologies, e.g., additive manufacturing.

Technical Committee: TC 11, High Temperature Mechanical Testing Committee

To ensure safety, reliability and durability of materials and components, it is vital to improve knowledge and understanding about their internal structure, mechanical properties and behaviour in response to in-service variables (e.g. mechanical, thermal, and environmental) as well as materials related variable (e.g. precipitates).

The scope of this symposium is to bring together scientists and engineers from different communities to discuss the latest developments in the fields of material characterisation and testing in harsh environments such as high temperature, complex loading, hydrogen, etc. A strong focus is placed on methods, challenges, and improvements of testing materials in harsh environments.

Technical Committee: TC-17, Non-Destructive Evaluation

TMerging information technology and automation characterizes the fourth technological revolution. This development appears as a rule in the field of NDE, called NDE 4.0. The NDE community started intensive and coordinated activity around the world. This process means a real paradigm shift: it changes the economy, changes the NDE, requires dramatic changes in education of the new generation in NDE and structural integrity assessment.

The Thematic symposium intends to get an insight into the most important elements of this process and to show the way forward. Content will cover the safety of engineering structures and components, relation of safety and NDE 4.0, techniques of NDE 4.0 (digital twin, machine learning, remote NDE, smart NDE, robotics, artificial intelligence, simulation…) and how they can serve structural integrity assessment.

Laser welding, additive manufacturing and laser shock peening are innovative technologies that can be used to manufacture load-bearing metal structures and improve their damage tolerance behaviour. This thematic symposium deals with the fatigue and fracture behaviour of laser-welded and processed metallic materials. One focus is on the characterisation and modelling of fatigue and fracture behaviour, taking into account inhomogeneous microstructures and residual stresses. Another focus is the use of advanced residual stress engineering techniques, such as laser shock peening, to improve damage tolerance and extend service life as well as to repair local damages. In this regard, the fatigue life prediction methods considering residual stresses play an important role.
