剪せん断だん安あん定てい性せい

noun

shear stability

Technical term used in materials science, fluid mechanics, and engineering to describe a substance's resistance to deformation under shear stress.

• この潤じゅん滑かつ油ゆは剪せん断だん安あん定てい性せいが高たかいため、高こう温おんでも粘ねん度どが低てい下かしにくい。

  This lubricant has high shear stability, so its viscosity is less likely to drop even at high temperatures.
