Abstract The paper follows the analyse of the connections between the constructive, working parameters, the annual energy consumptions and the energy quantity included in fitting out; it will formulate a methodology of establishment of the optimum values of the parameters of admeasurements of the pumping stations for the setting under pressure, of pipes networks, what ensure an optimum consumption of energy during of duty of the fitting out (the operational energy and the included energy in the networks, equipment and constructions), of the conditions after that it can be obtained. It will follow the generalization of the solutions of increase of… More >

Abstract Previous attempts to track skeletal kinematics from sequences of images acquired using biplane dynamic radiography report challenges in automating the tracking technique due to image resolution issues, occlusion from segments appearing synchronously in the field of view and computational load. This translates into many hours of manual work to export the kinematics. The proposed new tracking method tackles the above problems and reduces the time to export kinematics from several hours to less than 3 minutes. More >

Abstract In this work, a new equation to predict the springback in the bending and rolling processes of metallic sheet is presented. This equation has been experimentally applied in the design of a wood truncated cone to form an aluminum sheet truncated cone. Kalpakjian's equation was also applied but Damian's equation has given the best performance. More >

Abstract Measuring the position, speed and acceleration of the moving elements of a mechanism usually involves external instrumentation that has to be attached to it, which is not always feasible. The method discussed here provides an alternative to measure these kinematics characteristics without modifying the components. To test the method in a controlled environment a four-bar mechanism was build. It was designed to be as thin as possible and to allow arbitrary changes in its lengths. Three commercial programs and a specially designed software (KIMA{\textregistered }) are used to record, analyze, measure, compute and verify the kinematics of the mechanism. More >

Abstract This paper addresses the mechanics of indentation-induced delamination of a coating on a multi-layered hollow cylinder, for application to toughness testing of thermal barrier coating (TBC) systems. An electron-beam physical vapor deposition (EB-PVD) TBC system has been analyzed through a contact finite element model using a standard conical indenter impressed vertically on the top of the cylinder. Two cylinder sizes used in thermal-mechanical fatigue tests in literature have been considered in the analysis, with outer radii of 5.11 mm and 3.08 mm, and inner radii of 3.00 mm and 0.97 mm, respectively. Two boundary conditions for the inner surface of… More >

Abstract Little is known about in vivo menisci loads and displacements in the knee during strenuous activities. We have developed a method that combines biplane high-speed dynamic radiography (DRSA) and a subject-specific finite element model for studying in vivo meniscal behavior. In a very controlled uniaxial compression loading condition, removing of the pressure sensor from the model can result in relatively large errors in contact and cartilage stress that are not reflected in the change of meniscal displacement.

Abstract This paper deals with the application of inverse concepts in drying. The objective of the paper is estimation of the moisture diffusivity of a drying body by using only temperature measurements. Potato and apple slices have been chosen as representative drying bodies with significant shrinkage effects. A mathematical model of the drying process of shrinking bodies has been applied. The Levenberg-Marquardt method and a hybrid optimization method of minimization of the least-squares norm were used to solve the present parameter estimation problem. More >

Abstract The most popular expression that considers the size effect showed in concrete structures is the size effect law of Bazant. This law depends on two coefficients G_f and c_f. For the experimental determination of these coefficients is necessary obtaining the ultimate loads, in three points bending tests, of notched beams with different sizes. In this work, a method to determine the coefficients about the results on identical beams varying the deep of the notch, is presented. The necessary values of loads are obtained by a numerical analysis with FEM that considers non linear behaviour of the concrete material. Next the… More >
