Abstract:

This paper presents test results of AA2519/TI6AL4V composite laminate structure and mechanical properties. The composite laminate was merged by explosive welding using a transition AA1050 alloy layer. The tested composite after formation was annealed, quenched in water and then aged to strengthen it. The heat treatment process was carried out in order to improve the physical and strength properties of the laminate. Weld endurance properties were determined through fatigue testing performed in constant total deformation amplitude (εac) conditions.The paper also describes the influence of test c

Abstract:

<p>Maternal health is a concept indicating the health of mothers during pregnancy, childbirth and the post-partum period. Recent literature indicates that the maternal mortality rate in Iran is 23 per 100,000 live birth. For every death, 20 to 30 mothers suffer from chronic and acute illnesses arising from pregnancy and delivery; therefore, using a valid and reliable indicator will help researchers assess maternal health more precisely. In this longitudinal study, attempt has been made to compare mothers’ health status by using a subjective tool for evaluating the Physical-Maternal Healt

Striation spacings were in accord with da/dN values at the higher levels of K investigated, but at low K levels striation spacings were larger than the corresponding da/dN values. The percentage of the fracture surface containing striations varied with the K level, ranging from less than 1 % at low K levels to 80 % at higher K levels. The reason for the discrepan

Dental implants are becoming increasingly used in current dental practice. This increased demand has motivated manufacturers to develop varieties of product through design, but also looking for new materials used to improve surface characteristics in order to obtain a better osseointegration. But the increase in the use of implants goes to a consequent increase in the number of failures. These failures are caused either by treatment complications (peri-implantitis), by fatigue breakage under mechanical over-stress, by defective raw material, or due to errors during the insertion procedures.

A preceding study of the competition between fracture modes in monolithic brittle materials in cyclic loading with curved indenters in liquid environments is here extended to brittle layers on compliant substrates. The fracture modes include outer and inner cone cracks and radial cracks that initiate from the near-contact zone and penetrate downward. Outer cone cracks are driven by stresses from superposed Hertzian and plate flexure fields; inner cone cracks also grow within these fields but are augmented by mechanical driving forces from hydraulic pumping into the crack fissures.

In this study, a numerical method is developped to simulate fatigue crack growth. This method is based on a numerical coupled analysis using a cohesive zone modelling under cyclic loading in order to develop a coupled predictive approach of the crack growth. First, we present this damage law, then its validation by a convergence study of the solution with mesh size. We apply this model to the crack growth calculations in the case of a smooth specimen with a precracking made with a single crystal superalloy.

Abstract:

RESUMO: As fibras vêm sendo muito utilizadas para reforçar o concreto, e hoje, existe uma grande variedade delas, por exemplo, fibras de polipropileno, fibras sintéticas, fibras com baixo teor de carbono, e fibras de polietileno. O emprego das fibras nas misturas cimentícias promove diversas melhorias ao concreto armado, como, aumento da resistência à fadiga e ao impacto; tenacidade à flexão; aumento da capacidade de absorção de energia, que transferem tensões através de fissuras, fazendo com que reduza sua propagação e expansão; e maior ductilidade, pois em concretos não reforçados, após a pr

Abstract:

A 40-year-old female presented with cough, exertional dyspnea, abdominal pain with distention, fatigue, dry eyes and dry mouth. Past history revealed asthma. Physical examination was normal except for tachypnea. We found leukocytosis, azygos fissure on chest X-ray along with normal pulmonary function tests and arterial blood gases. Thorax computed tomography (CT) revealed bronchiectasis and ground glass opacities in both lungs. Abdominal CT demonstrated thrombosed proximal splenic artery aneurysm. Further diagnostic procedures were done and according to the positive Schirmer test and compatibl

Abstract:

During their operational use the aeronautic structures can be submitted to relatively moderate cyclic loads and more rarely to stern loads. These last can generate residual stress field, which will influence the in-service behaviour. Otherwise, residual stress field can be created in a voluntary way by a specific treatment (compressive stresses). They permit to improve fatigue tolerance behaviour. This illustrates the importance of the study of the structure behavior under residual stresses, and the need to consider them in numerical simulations. The objective of this work is to develop a nume
