Concept, etiology, and pathomechanics of hallux rigidus
Journal of the Foot & Ankle, 2021 There is a continuous anatomical, functional and pathomechanical roadmap from functional hallux limitus to hallux rigidus. Although many etiologies for hallux rigidus have been studied it is very probable that it has a primary origin with less-than-ideal

Interface roughness effect on friction map under fretting contact conditions [PDF]
, 2010 In many industrial applications where fretting damage is observed in the contact (e.g. rotor/blade, electrical contacts, assembly joint, axe/wheel, clutch) the external loadings or geometry design cannot be changed. Therefore, the surface preparation and
