This research studied the mechanical properties of orange and pomegranate shells powdersreinforced unsaturated polyester with different weight fractions %Wf. The compositespecimens were prepared by hand lay-up technique and sectioned according to (ASTM)for tensile, impact, bending and compression tests to obtain modulus of elasticity, ultimatetensile strength, elongation percentage, compression strength, impact energy and fracturetoughness of the composite specimens. The results showed that the composite specimensreinforced with pomegranate shells powder give high mechanical properties compare

Abstract:

Nanostructured Ti5Si3–TiC–Ti3SiC2 and Ti5Si3–TiC composites were in situfabricated through the spark plasma sintering (SPS) technique using Ti and SiC powders as reactants. It was found that the composites could be prepared in arelatively short time (6 min at 1260 °C) above 98% theoretical density. The phase constituents and microstructures of the samples were analyzed by x-ray diffractionand observed by scanning electron microscopy. Transmission electron microscopywas used for detailed microstructural analysis. The results showed that the reaction products mainly consisted of Ti5Si3 and TiC p

Abstract:

Pipelines are one of the most convenient and effectiveways of transporting petrol over a long distance. The environmentapplies, beyond extremely high external pressures, lowtemperatures and intensive corrosive process, the occurrence ofdefects on the pipe body, which compromises the structuralintegrity of pipelines leading to catastrophic failures. The mainmodifications concern the mechanical resistance, toughness at lowtemperatures weld ability and resistance to embrittlement relatedto hydrogen. Among mechanical characteristics, the fracturetoughness is very important for pipeline steels in d

Abstract:

As the demand for fossil fuels increases, pipelines are constructed in inhospitable areas. Underthese conditions, not only the strength but also the deformability of the pipelines becomes crucial. A strainbased design (SBD) procedure needs to be established. Traditional stress based approaches to evaluatedefect tolerance lead to conservative predictions. There is a need to accurately define the fracturetoughness of the pipeline steel and assess the criticality of weld defects under strain based conditions. Thispaper focuses on the implementation of the unloading compliance method to determine

In the structure of the alloy, two-phase eutectic regions are observed, which are a LaB6 matrix filled with cylindrical VB2 fibers up to 2 μm in diameter or extended VB2 crystals with a complex cross-section and an equivalent diameter of up to 10‒15 μm. The Vickers hardness and the fracturetoughness were determined, and the relationship between these characteristics and the load on the indenter, the direction of load application, and the typ

Abstract:

We provide a brief review of our recent studiesconcerning the effects of various mechanisms of plasticdeformation of nanocrystalline materials on their fracturetoughness. We consider both conventional deformationmechanisms, such as lattice dislocation slip, and the deformationmechanism pronounced mostly in nanocrystalline solids, such asgrain boundary (GB) sliding and migration. We demonstrate thatwith a decrease in grain size, the effect of conventional latticedislocation slip on fracture toughness enhancement significantlydecreases. At the same time, for nanocrystalline solids withsmallest g

Background: Water sorption is one of the concern regarding acrylic resin denture base materials since itmight affect the dimensional stability of the prosthesis, furthermore the absorbed water may dramaticallycompromise the physical and mechanical properties. Methods: Three different commercial denture basematerials (heat-curing acrylic resin) available in local markets were used (Vertex, Ivoclarw and Luxacryl)to evaluatewater sorption and the effect of dry andwet environment on the fracture toughness ofthese materi-als. Water sorption test was carried out according to international orga

Les essais de ténacité permettent de mesurer les propriétés de résistance d'un matériau vis-à-vis de l'amorçage et de la propagation de fissure. La réalisation de ces essais nécessite l'utilisation d'éprouvettes suffisamment grandes afin de mesurer une propriété valide. Cependant, il existe de nombreux cas pour lesquels il n'est pas possible d'obtenir des éprouvettes de dimensions suffisantes. En combinant une approche expérimentale et la simulation, cette thèse vise à développer des méthodes de mesure de la ténacité d'un matériau ductile à l'aide de petites éprouvettes.
