Technical Committees TC02: MICROMECHANISMS

Report of Activities In 2025, ESIS Technical Committee 2 (TC2) held a dedicated meeting during the 11th International Conference on Materials Structure & Micromechanics of Fracture (MSMF11), which took place on 23–25 June 2025 in Brno, Czechia. This event provided an excellent platform for presenting and discussing recent developments in fracture mechanics, microstructural characterisation, and modelling. Selected papers from MSMF11, including several contributions associated with TC2, have been published in Procedia Structural Integrity, Volume 74. Looking ahead, TC2 will continue its activities in 2026 by organising a mini-symposium within the 25th European Conference on Fracture (ECF25), to be held in Athens on 6–11 September 2026. This mini-symposium will bring together international researchers to share new insights into fracture processes, experimental advances, and modelling approaches relevant to the aims of the Technical Committee. The invitation for this event has been distributed to all registered TC2 members via the online platform and is appended on the next page. Andrey Jivkov Andrey Shanyavsky 1. Objectives of TC3 (1.1) Organisation of the Thematic Symposium on “Fracture and Fatigue in Additively Manufactured Materials: Mechanisms, Modelling and Performance Optimisation” (chaired by Professors Sabrina Vantadori, Camilla Ronchei and Andrea Zanichelli, Parma, Italy) at the Fourth European Conference on the Structural Integrity of Additively Manufactured Materials, Vicenza (Italy) & Web, 18th to 20th February, 2026. The Thematic Symposium will explore the challenges related to the mechanical reliability of components produced by Additive Manufacturing (AM). It will focus on how intrinsic defects, process parameters, anisotropy, and surface roughness will affect fracture and fatigue behaviour, influencing safety and durability. The symposium will welcome theoretical, experimental, and numerical contributions on fracture and fatigue mechanisms in metals, polymers, ceramics, and composites. Key topics will include the effects of defects and microstructure, post-processing treatments, in-situ testing, computational modelling, topology optimization, corrosion-fatigue, and certification of AM parts. International experts will present research and case studies from aerospace, biomedical, automotive, and civil engineering sectors. The event will be linked to the MUR PRIN 2022 PNRR project, funded by the European Union – NextGenerationEU, which will develop innovative methodologies for fatigue design of metallic AM components. (1.2) Organisation of the Special Session on “Bridging Physics and Data: Experimental, Analytical, Numerical, and AI Approaches to Composite Fatigue and Fracture” (chaired by Professors Sabrina Vantadori and Daniela Scorza, Parma, Italy) at the 29th International Conference on Composite Structures, Cagliari (Italy), 22nd to 26th June, 2026. The Special Session will focus on the complex interaction between physical mechanisms and data-driven methods in studying the fatigue and fracture of composite materials. It will aim to unite researchers and engineers from academia and industry to develop innovative approaches for modelling, testing, and predicting TC03: FATIGUE OF ENGINEERING MATERIALS AND STRUCTURES
