Investigating the effect of Al2O3-TiB2/Fe complex reinforcement (CCMR) on the mechanical properties of aluminum composites was the goal of this study. For this purpose, the Al2O3-TiB2/Fe reinforcement powders were synthesized during milling and subsequent annealing. Different volume percentages of the produced reinforcement powders (1.25, 2.5 and 5 vol.%) were added to aluminum matrix, mil...
Al7075 alloy reinforced with h-Boron Nitrate (BN) composites were processed by stir casting technique. The produced composite was subjected to microstructural studies using OLYMPUS -BX51M, tensile, hardness, density and wear tests. Tensile strength and hardness were found to increase by 12.8% and 20% respectively due to increased dislocation density with the addition of reinforcement. Microstru...
This paper presents the results of a series of small-scale model tests and numerical analyses conducted on circular and ring model footings located near geogrid reinforced sand slopes. Layers of geogrid were used as reinforcement. For numerical analyses Finite Element Method (FEM) was used. The effects of reinforcement depth, size, number of layers, and the horizontal distance between reinforce...
Background and Aim: The structural rehabilitation of a pulpless tooth is critically important to ensure a successful restorative outcome following endodontic treatment. A post and core is often indicated for the retention and reinforcement of the final restoration. But, the clinical situation is significantly challenging if the root exhibits immature development or there is a thin root wall tha...
Effect of Load Eccentricity on Stress Condition of Butt Welded Joint with Asymmetrical Reinforcement
Abstract An analytical method for determination of a stress condition butt welded thin-gauge plates with asymmetrical reinforcement is developed. The proposed allows take into account the effect load application eccentricity on tensile concentration factor (SCF) in weld root zone. It presented that bending stresses, caused by this eccentricity, result increasing total stresses up to 75%. result...

recognizing the importance of the advertising in brand reinforcement and brand credibility, the authors conduct the present research for understanding the customers’ emotional responses toward the brand reinforcement and credibility and its effect on the perceived values and behavioral intentions. hypotheses were tested on data collected from 467 customers of mellat bank in semnan province in i...
limit to the tension reinforcement ratio ( ρ) in flexural high strength reinforced concrete (hsrc) members is based on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state. however, the provisions for the total amount of longitudinal reinforcement ratio ( ρ and ρ’) are not associated with any rational derivation. in this paper, a quantitative ...
