Aspects Concerning Contact Stresses from a Dental Articulator Joint
(UDJG, 2010)
A dental articulator is a mechanical device, which simulates the temporomandibular joint (TMJ). The articulator is important because it replicates the basic revolve action of the upper and lower mandibles, as well as ...
Upon Fretting Behaviour in a Hertzian Point Contact
(UDJG, 2010)
Fretting is known as a wear process occurring in a small amplitude cyclic motion of two solid contacting surfaces and it can affect the fatigue resistance of the material, inducing wear and cracking. The kinematics ...
Numerical Modelling of 3D Impact
(UDJG, 2010)
The paper presents a virtual device designed for studying tri-dimensional impact. The main goal of the work is to present a solution for finding the coefficient of restitution for the tri-dimensional case of a sphere ...
