Remarks on orthotropic elastic models applied to wood
(2006-07-01)
Wood is generally considered an anisotropic material. In terms of engineering elastic models, wood is usually treated as an orthotropic material. This paper presents an analysis of two principal anisotropic elastic models ...
Photoelastic comparison of single tooth implant-abutment-bone of platform switching vs conventional implant designs
(2011-03-01)
Objectives: The maintenance and stability of peri-implantar soft tissue seem to be related to the crestal bone around the implant platform and different implant designs connections might affect this phenomenon. The aim of ...
Prospects for the use of municipal tree pruning wastes in particleboard production
(2013-09-01)
The purpose of this study was to evaluate the physical and mechanical properties of particleboard made with pruning wastes from Ipê (Tabebuia serratifolia) and Chapéu-de-Sol (Terminalia catappa) trees. Particleboards were ...
Effect of thermal treatments on tensile strength of commercially cast pure titanium and Ti-6Al-4V alloys
(2005-08-01)
Heating titanium structures is assumed to relieve tensions induced by the casting process as well as possibly optimizing some mechanical properties. The aim of this investigation was to evaluate the effect of thermal ...
Relation between the compaction rate and physical and mechanical properties of particleboards
(2005-07-01)
The compaction rate, the relation between the density of the wood panel and the density of the wood used for producing the particles, is an indicator of the product's densification. Among the various types of wood panels, ...
Tensile strength and histological changes of abdominal aorta of malnourished rats
(1995-01-01)
The resistance of the abdominal aorta of rats after 6, 7 and 8 weeks of malnutrition, compared with control animals, was evaluated by longitudinal tensiometry. Weakness of this vessel in malnourished rats was demonstrated; ...
Influence of Wood Moisture Content on the Modulus of Elasticity in Compression Parallel to the Grain
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2012-03-01)
Brazilian Standard ABNT NBR7190:1997 for timber structures design, adopts a first degree equation to describe the influence of wood moisture content. Periodically, when necessary, the referred standard is revised in order ...
Effect of thermocycling on bond strength and elasticity of 4 long-term soft denture liners
(Mosby, Inc, 2002-11-01)
Statement of problem. Two problems found in prostheses with soft liners are bond failure to the acrylic resin base and loss of elasticity due to material aging.Purpose. This in vitro study evaluated the effect of thermocycling ...
