The Impulse Manufacturing Laboratory (IML) is Professor Glenn Daehn's research group. IML is part of the Department of Materials Science and Engineering at The Ohio State University. For nearly 30 years, our research has focused on the development of novel manufacturing solutions using impulse-based processes. We found that by moving metals at high speeds, we can shape and join materials in unique ways that solve real-world problems. Impulse-based metalworking describes a wide range of processes that are fundamentally different than the metalworking processes that are commonly used today. Impulse metalworking processes typically utilize high pressures and short duration impulses that can be adapted to form, cut, join, weld, and emboss metals using lighter and more agile equipment. To drive the impulse based processes, IML currently utilizes a range of experimental equipment including capacitor banks, most of which were designed and developed in-house. These capacitor banks provide pulsed power for impulse processes driven by exploding conductors and magnetic pulses. We possess a number of experimental chambers designed to perform the operations described above with a variety of material constraints and instrumentation. High strain rate processes are also characterized using advanced diagnostics, particularly Photon Doppler Velocimeter (PDV). IML has machining capabilities for custom tooling and fixturing, including CNC milling, turning, and more. Our unique experimental capabilities are supplemented with academic and industry partner expertise in characterization techniques like SEM, EBSD and TEM, as well as numerical modelling for simulation of dynamic materials science phenomena.
