Conferences
European Conference on Residual Stresses (ECRS)
The European Conference on Residual Stresses (ECRS) addresses experimental methods, modelling, and industrial applications of residual stresses. Scientists, PhD students, and engineers from academia and industry attend. Previous editions were held in Karlsruhe (1983), Darmstadt (1990), Frankfurt/Main (1992), Cluny (1996), Delft (1999), Coimbra (2002), Berlin (2006), Riva del Garda (2010), Troyes (2014), and Leuven (2018).
This gathering brings together scientists, students, and engineers with a shared interest in Residual Stresses, a phenomenon that affects the physical properties of materials and surfaces across various scales. While its core focus lies in mechanical engineering and materials science, Residual Stresses also hold relevance in solid-state physics, life sciences, geology, and the chemical reactivity of solids. Managing residual stresses can unlock improved material and structural properties, such as enhanced fatigue life and geometrical stability. The analysis of residual stresses, being a highly sensitive parameter influenced by micro/nano-structure, provides valuable insights into the history of materials and structures. This conference offers an interactive platform for experts from diverse disciplines including mechanics, physics, optics, chemistry of solids, manufacturing, diffraction, and engineering. Attendees can exchange their perspectives and share recent advancements through experimental, theoretical, and numerical approaches.

Abstracts will be solicited for (but not limited to) the following topical programs:
- Additive Manufacturing:
Additive manufacturing (AM) allows production of complex parts from simple preforms, but preform joining involves high temperatures and cyclic heating that drive residual stress fields. Residual stresses can impact manufacturing, through in-process cracking or distorted geometry, as well as in-service performance relative to fatigue, corrosion, and other failure mechanisms. This symposium on residual stresses in AM is intended to gather researchers and engineers who will lay out the state of the art and discuss directions for further work. It is also intended to connect researchers and industry experts working in this and related areas.
- The Contour Method at 25 Years:
The contour method was first presented 25 years ago at ICRS 6 in Oxford, UK in 2000. This symposium will cover the developments in technique and understanding for the contour method since then, applications of the contour method, and what the future holds.
- Correlation Among Methods: Understand the relationships between different measurement methods.
- Effects of Residual Stress
- Formation of Residual Stress Fields:
Examine their characteristics and influence on distortion, material response to loading, damage initiation and propagation, component performance, life, and failure.
- Industrial Applications and Issues
- Manufacturing Processes:
Investigate how various processes influence residual stress.
- Material Properties:
Delve into the impacts of residual stress on fatigue, corrosion, and stress corrosion cracking.
- Polymers and Composites:
Residual stress in polymers and composites affects mechanical performance, durability, and reliability due to factors like curing, thermal expansion mismatches, and processing conditions. It can lead to warping, delamination, and microcracking in critical applications across aerospace, automotive, and electronics. This symposium will highlight advances in characterization, modeling, and mitigation strategies to enhance structural integrity and longevity.
- Residual Stress Modification:
Learn about modifying residual stress through shot peening, heat treatment, and other methods.
- Residual Stress Measurement Methods:
Explore cutting-edge techniques for measuring residual stress.
- Residual Stress Simulation:
Explore advanced simulation techniques.
- Quantifying uncertainty in residual stress measurements: a cross-method perspective:
It is common practice among residual stress analysts to gain confidence in a measurement by using multiple techniques. Naturally, identical results are not expected, since each technique is specialized in measuring stresses at different locations and on different dimensional scales. At the very least, however, the uncertainty intervals for the different measurements should be compatible with each other. How many times have we seen 95% confidence intervals systematically disjointed? Perhaps we are underestimating the actual uncertainty. This symposium aims to bring together scholars and practitioners in the field of residual stress for a discussion on this topic. Contributions related to any measurement technique are welcome, provided that an evaluation of the associated uncertainties has been conducted—and ideally validated.
