1. PHYSICAL AND MECHANICAL PROPERTIES OF THE BAMBUSA VULGARIS AS CONSTRUCTION MATERIAL
ABSTRACT The fabrication of traditional construction materials consumes a large amount of energy, emits pollutants, and utilizes nonrenewable raw materials. Therefore, it is important to reduce the environmental impact of construction through the use of eco-friendly materials, such as bamboo. This work presents the characterization of Bambusa vulgaris, which

3. Mechanical behavior of PVD coatings deposited on ADI
ABSTRACT In this work, the mechanical behavior of the coated ADI system is studied. For this purpose, single layer Ti and bilayer Ti/TiN and TiAl/TiAlN coatings, with different thicknesses, were deposited by the PVD technique of cathodic arc deposition on high strength ADI substrates using industrial and experimental devices. The characterization of the coat

4. Assessment of concrete anisotropy by means of compression and indirect tensile tests
Resumo Na análise e projeto estrutural de concreto armado, normalmente se assume que o material é isotrópico e homogêneo. As caraterísticas pontuais das estrutura, geralmente exercem pouca influência no comportamento das mesmas, portanto normalmente são desconsideradas. No entanto, existem muitas evidencias de que, na mesoescala, o concreto convencion

5. Evaluation of the stiffening mechanism based on micro-sized particle inclusions in laminated composites
Rigid particles have been incorporated into laminated composites, especially to enhance their bending performance attributed to the stiffening of the matrix phase (i) and the increased interlaminar shear resistance (ii). In order to better evaluate the improvement mechanism provided by the particulate inclusions, this work investigates the incorporation of m

6. Determination of Drilling Rate Index Based on Rock Strength Using Regression Analysis
Abstract: Drillability is influenced by many factors, including machine parameters and rock properties. The main machine parameters for drilling include rotational speed, thrust force, torque and flush pressure. The specific rock characteristics that affect penetration rate comprise uniaxial compressive strength (UCS), tensile strength, Young’s modulus, ha

7. Effect of Y Content on Properties of Extruded Zn-1.5Mg-xY Alloys for Medical Applications
In this work, we investigated the effect of yttrium(Y) on microstructure, the mechanical and corrosion properties and the cytotoxicity of Zn-1.5Mg-xY(x=0, 0.2, 0.5wt%) alloys prepared by casting and extrusion. The results showed that the microstructure of extruded Zn-1.5Mg-xY alloys consisted of α-Zn matrix, Mg2Zn11 particles and Y containing blocks. The te

8. Study of the compressive and tensile strenghts of self-compacting concrete with sugarcane bagasse ash
Resumo Neste trabalho foram avaliadas as resistências à compressão axial aos 3, 7 e 28 dias de idade e a resistência à tração aos 28 dias de idade, de corpos de prova de duas composições de concreto autoadensável (CAA). A diferença entre ambas, era a presença da cinza do bagaço da cana-de-açúcar (CBC), na taxa de substituição de 10% da massa

9. Mechanical Properties and Metallurgical Characterization of LM25/ZrO2 Composites Fabricated by Stir Casting Method
ABSTRACT Zirconia (ZrO2) dispersed aluminum alloy metal matrix composites produced by stir casting techniques. Using stir casting techniques, aluminium based composites with varying amounts of 3%, 6%, 9%, and 12% of zirconia by weight are fabricated. The prepared samples were subjected to physical, mechanical,tribiology and microstructure investigation. The

12. Durability of Concrete After Fire Through Accelerated Carbonation Tests
Degradation of mechanical properties and durability of reinforced concrete structures occur when they are subjected to fire situations, depending on the characteristics of the material, fire duration and the ways of fire extinguishing. Mechanical properties such as compressive strength, tensile strength and elasticity modulus are some examples of typically a
