Non-Homogeneous Uncoupled Beam under Tip Loads
Nanocrystalline material in toroidal cores for current transformer: analytical study and computational simulations
Based on electrical and magnetic properties, such as saturation magnetization, initial permeability, and coercivity, in this work are presented some considerations about the possibilities of applications of nanocrystalline alloys in toroidal cores for current transformers. It is discussed how the magnetic characterist…
The Effect of the Hole Diameter on Residual Stress and Plastic Zone Expansion in Aluminum Metal-Matrix Laminated Plates
Study of the non-linear stress-strain behavior in Ti-Nb-Zr alloys
The aim of this work is to study the elastic behavior of some Ti-Nb-Zr alloys (Ti-8Nb-13Zr, Ti-13Nb-13Zr, Ti-18Nb-13Zr and Ti-41.1Nb-7.1Zr) developed to biomedical applications. These alloys were produced by arc melting under argon atmosphere. Uniaxial tensile tests, carried out in a MST servo-hydraulic machine, were…
Evaluation of the load carrying capacity of large cross section coniferous timber in standing structures
A total of 85 large section timber pieces (Pinus sylvestris L. and Pinus pinaster Alt.) found in a number of old buildings were visually analyzed and graded pursuant to Spanish standard UNE 56544 and German standard 4074. The object was to formulate a non-destructive method to reliably and effectively determine the me…
The Rheology of Blood Flow in a Branched Arterial System
Blood flow rheology is a complex phenomenon. Presently there is no universally agreed upon model to represent the viscous property of blood. However, under the general classification of non-Newtonian models that simulate blood behavior to different degrees of accuracy, there are many variants. The power law, Casson an…

A Mean Flow Model for Polymer and Fiber Turbulent Drag Reduction
We present a one-parameter model that fits quantitatively the mean velocity profiles from experiments and numerical simulations of drag-reduced wall-bounded flows of dilute solutions of polymers and non-Brownian fibers in the low and modest drag reduction regime. The model is based on a viscous mechanism of drag reduc…

Evaporation Blocker for Cone-Plate Rheometry of Volatile Samples
We report on the design and implementation of an evaporation blocker for cone-plate and plate-plate geometries. In addition to minimizing sample evaporation by trapping the saturated vapor inside a sample chamber, an important feature of the evaporation blocker is the suppression of solvent transport through condensat…

The mechanism of changes in the surface layer of grey cast iron automotive brake disc
The aim of the study was to create a model, describing the run of tribological processes in the surface layer of grey cast iron automotive brake discs. Grey cast iron discs mating with non-asbestos organic brake pads were chosen for the investigations, as the most widely used materials in car brakes. Samples for surfa…
Operating characteristics of heavy loaded cylindrical journal bearing with variable axial profile
During the operation of turbounit its bearings displace as a result of heat elongation of bearings supports. It changes the static deflection line of rotor determined during assembly of the turbounit, causing an increase in the stresses on the bearing edges and a decrease in the dynamic state of the machine. One of po…
Theoretical and experimental study of carburisation and decarburisation of a meta-stable austenitic steel
Metastable austenitic stainless steels are known to undergo a partial transformation of austenite to martensite as a consequence of plastic deformation. In the case of cyclic loading, a certain level of plastic strain must be exceeded, and phase formation takes place after an incubation period, during which the necess…
Constant load creep data in air and vacuum on 2.25Cr-1Mo steel from 600 °C to 700 °C
Creep results on 2.25Cr-1Mo were obtained at 600 °C, 650 °C and 700 °C at five stress levels, under constant load, in air and vacuum. Two chambers were specially developed for carrying out creep testing in controlled environment, with the possibility of accommodating inside them the load train, the extensometry system…

Surface processing to improve the fatigue resistance of advanced bar steels for automotive applications
With the development of new steels and processing techniques, there have been corresponding advances in the fatigue performance of automotive components. These advances have led to increased component life and smaller power transfer systems. New processing approaches to enhance the fatigue performance of steels are re…
