Joona Vaara

Joona Vaara is a Doctoral Researcher affiliated with the Doctoral Programme in Built Environment. His research focuses on tribology, materials science, and fatigue analysis, particularly investigating fretting degradation, short crack behavior, and material responses under cyclic loading. Collaborations include studies on quenched and tempered steel, rough surface effects, and lubrication dynamics.

Key research interests include fretting wear mechanisms, fracture mechanics, and the interplay between microstructural barriers and material fatigue. His work has been published in journals like Tribology International and International Journal of Fatigue, with notable contributions to cyclic R-curve analysis and probabilistic modeling of material behavior.

Publications highlight advancements in understanding surface interactions, fatigue limits, and lubrication effects, contributing to improved material durability in mechanical systems.
