Rheological models for lithium and calcium greases
Mechanics, 2006 This paper presents the investigation of the rheological properties and the microscopic structures of two common greases: UM185Li2 - lithium grease and U95Ca2 - calcium greases, with NLGI grade two. The experimental apparatus used were a cone-and-plate rheometer for the rheological properties of the greases and an electronic microscope for the ...
