Influences of microcontact shape on the state of a frictional interface
Tom Pilvelait, Sam Dillavou, Shmuel M. Rubinstein
The real area of contact of a frictional interface changes rapidly when the normal load is altered, and evolves slowly when normal load is held constant, aging over time. Tradition…

Shear Destruction of Frictional Aging and Memory
Sam Dillavou, Shmuel M Rubinstein
We simultaneously measure the static friction and the real area of contact between two solid bodies. Under static conditions both quantities increase logarithmically in time, a phe…

Virtual Frame Technique: Ultrafast Imaging with Any Camera
Sam Dillavou, Shmuel M Rubinstein, John M Kolinski
Many phenomena of interest in nature and industry occur rapidly and are difficult and cost-prohibitive to visualize properly without specialized cameras. Here we describe in detail…
