Elastic-Plastic Contact Modeling. Part I: Algorithm Overview and Assessment of Plastic Strain Increment
(UDJG, 2010)
A fast algorithm for elastic-plastic contact simulation is overviewed in this paper. Betti’s reciprocal theorem is employed to assess surface normal displacement and stress state in an elastic half-space in the presence ...
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 ...
Tribological Aspects of Electrode-Elastomer Contact
(UDJG, 2010)
Dielectric elastomers (DE) are soft polymers based smart materials that may be potentially employed in applications such as actuation, sensing and energy harvesting. The performance of dielectric elastomer actuators (DEA) ...
Elastic-Plastic Contact Modeling. Part II: Numerical Simulations and Program Validation
(UDJG, 2010)
Elastic plastic spherical contact is simulated using an algorithm proposed in a companion paper. Materials of contacting bodies are assumed to have different behaviours: rigid (R), elastic (E), elastic-plastic with isotropic ...
The Neuber’s Rule and a Correlation Between Fretting Fatigue and Plain Fatigue
(UDJG, 2010)
Based on these experimental observations and on the remark that any small change on the discontinuity geometry has a significant effect on the stress distribution around it, a stress concentration factor is mandatory to ...
Microdefects Analysis of Dental Contact Surfaces
(UDJG, 2010)
The tribological processes influence the behaviour of the biocontacts between biological bodies, between biomaterials or between biological bodies and biomaterials. Whether natural or artificial, any biocontact is the locus ...
Experimental Research for Measuring Friction Forces from Rod Sealing at the Hydraulic Cylinders
(UDJG, 2010)
The paper presents experimental equipment and research results conducted by Hydraulics and Pneumatics Research Institute INOE 2000-IHP Romania in cooperation with Institute PPRIME – University of Poitiers France, in order ...
Multiwall Carbon Nanotubes Coated with Iron (iii) Oxide and Improved Dispersion Method for Nanostructured Polymer Composites
(UDJG, 2010)
The aim of this paper is to describe a method of coating with ceramic molecular layer, in order to obtain a MWCNTs (multiwall carbon nanotubes) functionalized surface, chemical bond energy increase and physico-chemical ...
Research Issues on Punch - Circular Plate Elastic Contacts
(UDJG, 2010)
Circular plates enter into the category of finite dimension bodies. Solutions regarding the displacements and stresses, which appear at the contact involving finite dimension bodies and also numerical and analytical results ...
