Dynamic Contact with Signorini’s Condition and Slip Rate Dependent Friction
Existence of a weak solution for the problem of dynamic frictional contact between a viscoelastic body and a rigid foundation is established. Contact is modelled with the Signorini condition. Friction is described by a slip rate dependent friction coefficient and a nonlocal and regularized contact stress. The existence in the case of a friction coefficient that is a graph, which describes the j...
متن کاملTwo Experiments on the Perception of Slip at the Fingertip
This paper describes the results of two experiments that investigate relative motion between a surface and the fingertip (slip) as part of a larger program of research on “fingertip haptics.” The primary intent of both experiments is to evaluate the importance of relative motion with respect to perceiving surface velocity. The perception of surface velocity is crucial to dexterous control and o...
متن کاملStabilizing stick-slip friction.
Even the most regular stick-slip frictional sliding is always stochastic, with irregularity in both the intervals between slip events and the sizes of the associated stress drops. Applying small-amplitude oscillations to the shear force, we show, experimentally and theoretically, that the stick-slip periods synchronize. We further show that this phase locking is related to the inhibition of slo...
متن کاملPartial squeeze film levitation modulates fingertip friction.
When touched, a glass plate excited with ultrasonic transverse waves feels notably more slippery than it does at rest. To study this phenomenon, we use frustrated total internal reflection to image the asperities of the skin that are in intimate contact with a glass plate. We observed that the load at the interface is shared between the elastic compression of the asperities of the skin and a sq...
متن کاملFriction Fluctuations and Friction Memory in Stick-Slip Motion.
We demonstrate that friction is not always an exact number. In a simple lubricated system (atomically smooth mica separated by molecularly thin films of squalane), sinusoidal shear forces were applied for millions of cycles. The kinetic friction increased steadily over repetitive cycles and collapsed intermittently to the average value. Individual slip cycles also consisted of a cascade of smal...
