Area-Contact Haptic Simulation
2003This paper presents the haptic interaction method when the interaction occurs at several points simultaneously. In many virtual training systems that interact with a virtual object, the haptic interface is modeled as a point. However, in the real world, the portion interacting with real material is not a point but rather multiple points, i.e., an area.

The actual contact area in viscoelastic contact problems
Polymer Mechanics, 1972The effect of the viscoelastic properties of polymers on the formation of the actual contact area is analyzed with reference to a rod model of the rough surface. The proposed time dependence of the actual contact area has been verified experimentally by an optical method for surfaces with different finishes (▽ 4, ▽ 8) and for different materials ...

Contact areas in the thumb carpometacarpal joint
Journal of Orthopaedic Research, 1995AbstractThe thumb carpometacarpal joint is a common site of osteoarthritis. It has been hypothesized that peaks of localized stress on the dorsoradial or volar‐ulnar regions, or both, of the articular surfaces of the trapezium and metacarpal lead to erosion of cartilage and may be responsible for the progression of the disease.

Finger joint contact areas and pressures
Journal of Orthopaedic Research, 1985AbstractAlthough the joints of the index finger are similar geometrically and kinematically, the occurrence of degenerative joint disease is more frequent and severe in the distal interphalangeal joint. Much circumstantial evidence exists to suggest a mechanical cause for the observed differences in frequency.

Tibiofemoral Contact Area-Determination and Implications
The Journal of Bone & Joint Surgery, 1972We have presented a roentgenographic method of determining the area of contact of the femur on the medial and lateral tibial plateaus. The area of contact on both tibial plateaus decreases throughout the first 35 degrees of flexion. The average area of contact on the medial plateau was 1.6 times greater than the area on the lateral plateau.

Contact Area and Thermal Contact Resistance in an Ideal Bolted Joint: Part 1 — Study of Contact Area
CAE/CAD and Thermal Management Issues in Electronic Systems, 1997Abstract The contact area at the interface of a bolted joint was investigated analytically, experimentally and numerically. Consideration was restricted to an ideal two-plate model for which the interface was perfectly flat. The two plates made circular contact under uniform axisymmetric normal loading.

Contact Areas in Human Elbow Joints
Journal of Biomechanical Engineering, 1982The paper describes the results of in-vitro experiments to determine the contact areas in the elbow joint during different anatomical positions. The casting technique, using wax as a casting material, was used in this study. The shape and size of the contact areas change, in different elbow positions ranging from full extension to full flexion.

Dependence of Skin Permeability on Contact Area
Pharmaceutical Research, 2003We report that experimentally measured skin permeability to hydrophilic solutes increases with decreasing contact area between the formulation and the skin. Our results suggest that an array of smaller reservoirs should thus be more effective in increasing transdermal drug delivery compared to a large single reservoir of the same total area ...

Thermotactile thresholds at the fingertip: Effect of contact area and contact location
Somatosensory & Motor Research, 2010Thresholds for the detection of changes in temperature are used to indicate neuropathy, but a variety of different contact areas and contact locations are used. This study was designed to determine the effects of variations in contact area and contact location on both warm and cool thresholds at the fingertip.
