Aspects of Mechanical Behavior and Modeling of a Tropical Unsaturated Soil
The research studies the applicability of two elastoplastic models for the collapse prediction of the lateritic soil profile from Southeastern Brazil. These tropical soils have peculiar geotechnical behavior, due to their ...
Evolution of the mechanical properties of a tropical soil stabilized with lime and ash of rice rind
The ash of rice rind is a pozzolanic material that reacts with the calcium hydroxide (Ca (OH)2) forming bonding composites, when finely worn out and in water presence. Considering this behavior, the objective of the present ...
Hardness and compressive strength of indirect composite resins: effects of immersion in distilled water
(Blackwell Publishing, 2004-11-01)
The aim of this study was to evaluate the effect of ageing in distilled water on the hardness and compressive strength of a direct composite resin Z100, a feldspatic porcelain (Noritake) and three indirect composites ...
Remarks on orthotropic elastic models applied to wood
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 ...

Foaming of EVA/starch blends: Characterization of the structure, physical properties, and biodegradability
Foams produced from blends of an ethylene-vinyl acetate copolymer (EVA) with high VA (vinyl acetate) content (28%) and corn starch have been successfully fabricated using an improved compression molding technique. A detailed ...
INTRA-RING COMPRESSION STRENGTH OF LOW DENSITY HARDWOODS
(Universidad del Bío-Bío, 2006)
Compressive strength of dental composites photo-activated with different light tips
The aim of this study was to evaluate the compressive strength of microhybrid (Filtek™ Z250) and nanofilled (Filtek™ Supreme XT) composite resins photo-activated with two different light guide tips, fiber optic and polymer, ...
Study of an anisotropic polymeric cellular material under compression loading
(ABM, ABC, ABPol, 2012)
This paper emphasizes the influence of micro mechanisms of failure of a cellular material on its phenomenological response. Most of the applications of cellular materials comprise a compression loading. Thus, the study ...
Determination of in situ uniaxial compressive strength of coal seams based on geophysical data
(SPRINGER HEIDELBERG, 2009)
The central issue for pillar design in underground coal mining is the in situ uniaxial compressive strength (sigma (cm)). The paper proposes a new method for estimating in situ uniaxial compressive strength in coal seams ...
