Advancement of Integrated Digital Image Correlation, Integrated Digital Height Correlation, and Mechanical Shape Correlation
Johan Hoefnagels is Associate Professor at the department of Mechanical Engineering at the Eindhoven University of Technology (TU/e) in the Netherlands, after a BSc and MSc in applied physics and a PhD on advanced optical diagnostics in plasma physics. His current research activities focus on experimental-numerical micromechanics to unravel the micromechanical behavior of materials and material systems in order to achieve superior mechanical performance and durability at the scale of application. This is done in two ways: (i) by integration of micro-mechanical testing with in-situ microscopic characterization to elucidate the underlying deformation and/or failure mechanisms at the level of the microstructure and (ii) by intricate coupling of numerical simulations to experimental procedures using advanced data correlation routines that are developed in house. Topics of particular interest include: ductile damage and fracture, delamination and interface mechanics, miniaturization and size effects, thin film mechanics and MEMS, flexible and stretchable electronics, and hybrid and multi-phase materials.
Johan has (co-)authored 90 journal publications and over 100 refereed proceedings/book contributions; he has given more than 100 international presentations, of which over 30 invited and/or keynote, and organized 10+ international symposia. He has over two years of international research experience, built up during international visits to IMEC (Leuven, Belgium), SUNY (Albany, USA), NIST (Gaithersburg, USA), CSM (Golden, USA), and Harvard University (Cambridge, USA). He is Dutch representative of the European Structural Integrity Society (ESIS) and Editor-in-Chief of the journal of Strain.
