Introduction During operation, materials of structural elements are subjected to damage whose nature depends on the mode of loading and operating conditions (high and low temperatures, cyclic loading, corrosive environments, irradiation, etc.). The diagnostics of material damage and its description are highly important for developing methods to improve reliability, predict the residual life of structural elements, and optimise the physical and mechanical properties of materials. Investigations of damage accumulation in metals involve both the development of fundamental descriptions of this phenomenon and methods for assessing the strength and service life of structural elements, accounting for the full set of design and operational factors. VIII International Conference “In - service Damage of Materials: Diagnostics and Prediction”, organised under the auspices of the European Structural Integrity Society (ESIS), has a long history. Previous conferences were held in Ternopil in 2009, 2011, 2013, 2015, 2017, 2019, 2023. The main organisers of these conferences were Ternopil Ivan Puluj National Technical University, Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine, the Ukrainian Society on Fracture Mechanics (USFM), and the G.S. Pisarenko Institute for Problems of Strength of the National Academy of Sciences of Ukraine. The USFM presents Ukraine in the ESIS via the Ukrainian National Group. The DMDP 2025 was held online between 15-17 October 2025. This conference brought together leading scientists, researchers, and research scholars to share their experience, research results, and scientific ideas in key areas of fracture and damage mechanics, structural integrity assessment, and maintenance. It has become an interactive platform for discussing recent advances, trends, and practical challenges in fracture mechanics and structural integrity. The Conference hosted 112 presentations from Spain, Belgium, the United Kingdom, Germany, Poland, France, the Slovak Republic, Israel, Latvia,Brazil, Indonesia, Vietnam, South Korea, VIII International Conference “In -service Damage of Materials: Diagnostics and Prediction ” (DMDP 2025) Preface – In-service Damage of Materials: Diagnostics and Prediction Oleg Yasniy a, *, Olha Zvirko b , Volodymyr Iasnii a , Yuri Lapusta c a Ternopil Ivan Puluj National Technical University, 56 Ruska St., Ternopil 46011, Ukraine b Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine, 5, Naukova St., Lviv 79060, Ukraine c Université Clermont Auvergne, CNRS, Clermont Auvergne INP, Institut Pascal, F-63000 Clermont-Ferrand, France
