13. Estudo da inferência de carregamento em histórias de vôos simulados na liga de Al aeronáutico SAE-AMS 7475 T7351 / Loading study of inference in a simulated flights history using an SAE-AMS 7475 T7351 aluminum alloy.
The loading inference and the fractographic reconstruction of fatigue crack propagation rate in simulated flight stories, as Twist, mini-Twist, Falstaff and mini-Falstaff were investigated in this work. The studied material was an aluminum alloy SAE-AMS 7475 T7351. Tensile and hardness tests were carried out in order to determine mechanical properties, as we

14. Indicators of potentialities and performance of recycled aggregates of construction and demolition wastes in flexible pavaments / Indicadores de potencialidades e desempenho de agregados reciclados de resíduos sólidos da construção civil em pavimentos flexíveis
The solid residues produced during construction and demolition are generally considered useless and cause several social and environmental impacts when not disposed appropriately. Solid residues are often deposited irregularly, result in obstruction of drainage systems, and cause the proliferation of vectors of diseases. Some experimental programs undertaken

15. Experimental and numerical analysis of cold-formed steel angles under tension and connected with bolts / Análise experimental e numérica de cantoneiras de aço formadas a frio, sob tração e conectadas por parafusos
This work is an experimental and numerical study of cold-formed steel angles connected with bolts and under tension loading. Due to the non-uniform straining of the tension- member when connected to the gusset plate, a debilitating phenomenon, known as the shear lag, takes place. This phenomenon is also investigated in this research. For the calculation of t

16. Influência da dimensão e da sucção matricial no comportamento de fundações superficiais assentes em solo arenoso não-saturado / Size and matric influence in the behavior of shallow foundations in unsaturated sandy soils
The influence of matric suction and size of footings in the bearing capacity and settlement of shallow foundations in unsaturated sandy soils are analyzed. Fourteen plate load tests were performed in the first part of the research. Rigid metallic plates with diameters 0,20, 0,40, 0,80 m and one concrete circular footing with 1,50 m were used in the tests. Al

17. Stress-settlement curve prediction of plate load tests on unsaturated soil / Previsão da curva tensão-recalque de ensaios de placa em solo não saturado
Apresenta-se um método para a previsão da curva tensão-recalque a ser obtida em provas de carga em placa circular, instalada a diferentes profundidades e com vários diâmetros, para diversos níveis de sucção em solo não saturado. Também é proposto um procedimento para correção dos recalques medidos em ensaio com carregamento do tipo rápido, para

18. The utilization of a hand penetrometer in a collapsible soil and comparison with load tests in plate and in footing / Utilização de penetrômetro manual em solo colapsível e comparação com resultados de provas de carga em placa e em sapata
The objective of this work is to evaluate the use of a hand penetrometer to quantify the penetration resistance of a porous and unsaturated soil. The tests were done with suction monitoring, thus, it was obtained correlation between resistance of the penetrometer penetration and the soil suction. The values of rupture pressure obtained by the penetrometer te

19. Correlação de estrias de fadiga com espectro de cargas em liga de Al aeronáutica SAE-AMS 7475 T 7351. / Correlation of fatigue striation spacing to loading history in aeronautic Al alloy, AMS 7475 T7351.
This work discusses the relationship between striation spacing, i.e. the microscopic crack propagation rate, SL (local) e SP (projected), as measured in post-mortem fractographic inspection of fatigue fractured surfaces, and the macroscopic crack propagation rate, da/dN, as monitored during fatigue crack growth tests. Compact tensile specimens C(T) were extr

20. Resistencia a flexão de fixação em osteotomia de costela bovina, variando o numero, a localização e a extensão das placas
The aim of this study was to evaluate the stability fixation promoted by titanium plates and screws of 2.0mm system. It was done in vitro by using 2.0mm system in osteotomies carried out in bovine ribs thereafter submitted to bending test changing the number, the extension, and the location of the plates. From bending tests were obtained the load applied and

21. Determinação da rigidez e amortecimento equivalente proveniente do fluido escoando e interagindo com placas flexiveis : teoria e constatações experimentais
The understanding and modelling of the stiffness and the damping behavior of structures when subjected to a flow field, is still a very complex problem, dealing with the interaction of two major fields of mechanical sciences. The classical theory of elasticity deals with strains of flexible bodies under predefined external loads. Generally, the external load

23. Tratamento térmico mínimo do suco de laranja natural: estudo da viabilidade de armazenamento em latas de alumínio. / Fresh single-strength orange juice minimal heat treatment: storage viability in aluminium cans
In this research project, minimal heat treatment was studied for fresh single- strength orange juice. The juice was packaged in aluminum cans and stored at refrigerated temperature during 57 days concerning shelf life tests. The juice was processed using a plate heat exchanger at nominal pasteurization temperatures 80ºC and 85ºC and packaged in aluminum va
