Alívio de tensões residuais em juntas soldadas de caixa espiral de turbina hidraúlica
(Universidade Estadual Paulista (UNESP), 2014)
Medição de tensões residuais em juntas soldadas pelo processo de soldagem a arco elétrico com atmosfera gasosa (GMAW) utilizando ondas longitudinais criticamente refratadas (ondas LCR)
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-12-13)
Welding is a manufacturing process widely used in industry to join metal parts permanently.
However, the welding process may induce residual stresses, affecting the mechanical
performance of the component negatively. ...
Shear wave propagation in residual soil–rigid inclusion mixtures
(Elsevier Science Sa, 2019-02)
Residual and tropical soils are particulate materialswith a wide range of particle sizes. Usually these geomaterials have a fine particle matrix containing dispersed rigid inclusions that affect theirmechanical behavior. ...

Influence of cavosurface angle on the stress concentration and gaps formation in class V resin composite restorations
(2019-09-01)
The study aimed to evaluate the influence of cavosurface angle on stress concentration and gap formation in class V restorations. Cylindrical cavities 3 mm in diameter were prepared in forty-five bovine incisors, changing ...
Machining damage analysis of alumina in relation to thermal shock behavior
(Springer, 2010-04-13)
Machining damage of alumina disks with two different finishes, C and F, was analyzed with the aim of explaining the differences in their thermal shock responses. Thermal treatments designed to simulate conditions in thermal ...
Influence of shot peening and hard chromium electroplating on the fatigue strength of 7050-T7451 aluminum alloy
(Elsevier B.V., 2007-07-01)
Chromium electrodeposition is a technique for the production of functional coatings on engineering components. These coatings are extensively micro-cracked and present high level of hardness, resistance to corrosion and ...
