Mechanics Analysis of Rough Surface Based on Shoulder-Shoulder Contact

Effect of Using Tramadol on Shoulder Dislocation

An analysis of shoulder laxity in patients undergoing shoulder surgery.

BACKGROUND It has been recognized that there is a distinction between shoulder laxity and shoulder instability and that there is a wide range of normal shoulder laxities. Our goals were (1) to evaluate if the ability to subluxate the shoulder over the glenoid rim in patients under anesthesia would be more prevalent than the inability to do so, (2) to determine if patients with a diagnosis of in...

Contact mechanics for randomly rough surfaces

When two solids are squeezed together they will in general not make atomic contact everywhere within the nominal (or apparent) contact area. This fact has huge practical implications and must be considered in many technological applications. In this paper I briefly review the basic theories of contact mechanics. I consider in detail a recently developed contact mechanics theory. I derive bounda...

Impacts of Enhanced UI Feedback on Shoulder to Shoulder Computing

To examine the impacts of enhanced UI feedback on shoulder-to-shoulder computing, we conducted a study using a simple picture puzzle on a computer with one display, two mice, and one keyboard. After adding sound, color differentiation, status indicators, and a graphical history, the accuracy with which subjects reported the actions of the person sitting next to them increased significantly. Par...

Finite Element Simulation of Contact Mechanics of Cancer Cells in Manipulation Based on Atomic Force Microscopy

The theory of contact mechanics deals with stresses and deformations which arise when the surfaces of two solid bodies are brought into contact. In elastic deformation contact occurs over a finite area. A regular method for determining the dimensions of this area is Hertz Contact Model. Appearance of atomic force microscope results in introduction of Contact ...
