معرفی
Mikko Hokka is a Professor and Head of the unit in the Department of Materials Science and Environmental Engineering at the Faculty of Engineering and Natural Sciences, Tampere University. His research focuses on experimental characterization of material behavior under dynamic loading conditions, with particular emphasis on high and low temperature testing at high strain rates. He leads the Engineering Materials Science (EMS) group and is an active member of the DYMAT Governing Board since 2016.
His research interests include developing experimental methods for studying dynamic phenomena such as strain-induced phase transformations in materials, percussive drilling of rocks and concrete, plastic deformation in high entropy alloys, and the effects of adiabatic heating on plastic deformation using high-speed imaging techniques. Key areas of expertise are mechanical testing, digital image correlation, infrared imaging, and the application of the Split Hopkinson Pressure Bar.
His recent work spans dynamic material behavior, including investigations into phase transformations in steels, composite material failure under high strain rates, and geomechanical processes such as rock drilling. Hokka has also contributed to foundational texts like the 2024 anthology Dynamic Behavior of Materials, showcasing his leadership in advancing the field's theoretical and applied aspects.
Notable contributions include studies on adiabatic heating effects in metals, piezoelectric excitation of quartz in granitic rocks, and energy quantification in percussive drilling. This interdisciplinary work bridges materials science with geomechanics and engineering, addressing challenges in both industrial and fundamental research contexts.
