Design Principles
"Surface topography is a controllable design variable that significantly influences mechanical contact behavior."
In design practice, achieving specific mechanical performance often relies on material selection and bulk properties. This research highlights that surface topography itself is a critical design parameter, especially with advanced manufacturing techniques like additive manufacturing, allowing for precise control over how components interact at a microscopic level.
What This Means for Your Design
