MnM² lab - KU Leuven
Welcome to the website of the MnM² lab at the Department of Materials Engineering, KU Leuven!
Our team, under the supervision of prof. Joris Everaerts, performs research on micro- and nanomechanics of materials, in-situ nanomechanical testing and residual stress evaluation at very small scales.
We aim to develop novel test methodologies in order to study the mechanical and fracture behaviour of metals and to enable mechanical characterization of small samples such as coatings, thin layers and nanoelectronics in a range of environmental conditions.

The MnM² team
Akshay Mundayadan Chandroth
Ph.D. researcher
Akshay obtained his Master's degree in Materials Engineering at Chalmers University of Technology in Sweden after a bachelor’s in Mechanical Engineering at Amrita Vishwa Vidyapeetham in India. His PhD topic focuses on unraveling the link between microscale residual stresses and texture in Ti-6Al-4V using FIB-DIC residual stress analysis and other techniques.
Wout Van Wesemael
associated Ph.D. researcher
Wout's PhD topic is part of a project that aims at a multi-scale characterization of tooth enamel across species, supervised by prof. Fei Zhang from the Advanced Ceramics and Powder Metallurgy group and co-supervised by prof. Everaerts. He is collaborating with the MnM² lab to perform nanoindentation mapping experiments on tooth specimens.
Kento Takahashi
Ph.D. researcher
Kento obtained his Master's degree in Materials Science and Engineering at Toulouse INP-ENSIACET after an Integrated Preparatory Cycle (CP2I) at ECPM Strasbourg. His PhD topic is part of an FWO project that focuses on nanoscale testing of polishing-induced surface changes in metals, using mainly nanoindentation mapping and FIB-DIC techniques.
Aman Gupta
associated Ph.D. researcher
Aman obtained a VLAIO Baekeland mandate in collaboration with Amnovis to do a PhD on the development of a computation assisted material selection approach for multi-material metal additive manufacturing, supervised by prof. Kim Vanmeensel from the Material Aspects of Additive Production Techniques and Welding Processes group and co-supervised by prof. Everaerts. He is collaborating with the MnM² lab to perform nanoindentation mapping experiments on multi-material interfaces.
prof. Joris Everaerts
Head of MnM² lab
Joris Everaerts is an assistant
professor at the Department of Materials Engineering of KU Leuven since 2021. He
obtained his Ph.D. at the same university in 2017, after which he
worked as a post-doctoral researcher at the University of Oxford and at
EPFL in Switzerland.
Stefaan Lathouwers
associated Ph.D. researcher
Stefaan's PhD topic is part of a project that aims to achieve controlled processing of Functionally Graded Materials (FGM) through a Laser Direct Energy Deposition (L-DED) method, supervised by prof. Kim Vanmeensel from the Material Aspects of Additive Production Techniques and Welding Processes group and co-supervied by prof. Everaerts. He is collaborating with the MnM² lab to characterize the mechanical properties and deformation of gradient interfaces.
Infrastructure & techniques
Feel free to contact us for more information!
Electron microscopy
Our lab relies on the Core Facility Electron Microscopy of the Department of Materials Engineering, which contains a wide range of microscopes and preparation facilities. More info can be found by the clicking the link above.
FIB-DIC ring-core milling
We perform focused ion beam - digital image correlation (FIB-DIC) ring-core measurements to evaluate residual stresses in very small gauge volumes down to pillars of 1 µm in diameter. This includes depth-resolved measurements, enabling evaluation of near-surface residual stress variation with a depth resolution of <100 nm. Feel free to contact us for more information!
Advanced nanoindentation
Our state-of-the-art nanoindenter enables advanced CSM nanoindentation measurements across sample surfaces to achieve 'mechanical microscopy' or mapping of hardness and stiffness variation at the microstructural level.
In-situ nanomechanical testing
Our state-of-the-art nanomechanical testing device fits inside the vacuum chamber of electron microscopes, enabling a variety of measurements such as micropillar compression, microcantilever bending, MEMS characterization and more.
