Prof. Toshiharu Mizusho studies the effects of shock waves and air blasts on structures and biological tissues from the viewpoint of high-speed mechanics.
He has been involved in the development of blast simulation methods using shock tubes and detonation tubes, advanced methods for measuring excess pressure and deformation on structures, and numerical analysis methods for these methods.
In this context, he proposed and realized a detonation-driven blast simulator that can reproducibly simulate the hydrodynamic characteristics of a blast generated by a point explosion of a kilogram-weight explosive as a fundamental experimental device from an engineering viewpoint in blast injury research.
Furthermore, he established the high-velocity background Schlieren method (H-BOS method), developed the blast-responsive pressure-sensitive paint (B-PSP), and applied the digital image correlation method (DIC method) to realize a 4D visualization measurement method of the mechanical action of a blast with microsecond time resolution and sub-millimeter spatial resolution. As a result, he developed a full-field, quantitative measurement of blast overpressure and structural deformation, which had been dominated by point measurements.
His results contribute widely to the understanding of the high-speed mechanical effects of shock waves propagating in a medium on structures and biological tissues, and have great potential not only for explosion safety research but also for experimental methods in fluid science, materials science, and medical engineering.
These are cutting-edge research results, and they have made a great contribution to the Japan Explosives Society academically, and Professor Toshiharu Mizukaki is worthy of the Japan Explosives Society Paper Award.
