Material strength Laboratory

Ensuring safety and enhanced reliability of machines

Our laboratory researches screws, gears and other mechanical components from the perspectives of material and fracture mechanics. We aim to boost the reliability and strength of mechanical components used in automobiles, trains, planes and other vehicles. Recently, we have studied fatigue fracture and friction properties of bolts made from aluminum alloys or magnesium alloys, which will likely be used in next-generation vehicles, with the goal of developing new evaluation methods and fastening technologies.
