Friction torque in four contact point slewing bearings: Effect of manufacturing errors and ring stiffness
(Elsevier, 2017-02-24)
This work outlines a procedure for the determination of the interferences between balls and raceways in four contact
point slewing bearings due to manufacturing errors. The procedure is applied to a particular case and ...
A novel experimental procedure to determine the cohesive law in ENF tests
(Elsevier, 2019-01)
This study presents a novel method to determine the mode II cohesive law of unidirectional carbon fiber reinforced polymer laminates, employing the End Notched Flexure (ENF) test.
The fracture toughness in mode II (G) ...
Efficient assembly of bolted joints under external loads using numerical FEM
(Elsevier, 2018-05-16)
Several factors can cause leakages in a bolted flange connection, external loads being the
most important one. External loads such as those produced by misalignment introduce an
external axial load combined with a bending ...
Analysis of the DCB test of angle-ply laminates including residual stresses
(Elsevier, 2017-03-14)
[ES] Se propone un nuevo método para obtener la tasa de liberación de energía mediante la prueba de doble viga en voladizo para laminados de capas angulares. Se estudian dos secuencias diferentes, simétrica y antisimétrica. ...
A skid resistance prediction model for an entire road network
(Elsevier Ltd., 2020-11-30)
[EN]This article predicts the available minimum skid resistance in the road network of Biscay (Spain) with data collected in the summer season when friction values are at a minimum. Firstly, it was observed that pavement ...
An Improved Meshing Method for Shape Optimization of Aerodynamic Profiles Using Genetic Algorithms
(WILEY, 2008)
One of the basic problems in fluid dynamics shape optimization is mesh generation. When analysis is performed using the finite element method, meshes of sufficient quality need to be constructed automatically. This work ...
A feedforward controller for tuning laser cladding melt pool geometry in real time
(Springer, 2016-07-12)
In this paper, a feedforward proportional-integral (PI) controller is developed to effectively control and tune the laser cladding melt pool geometry in real time. Width setpoint is included in the computer numerically ...
Active flow control on airfoils by reinforcement learning
(Elsevier, 2023-11-05)
Active flow control is a widespread practice for airfoil aerodynamic performance enhancement. Within active flow control, reactive strategies are very effective, but the adequate design of these strategies is often complex. ...
FEM Subsystem Replacement Techniques for Strength Problems in Variable Geometry Trusses
(Elsevier, 2007-12-01)
This work presents the application of a procedure for replacing FEM subsystems with a high number of dofs (possibility of including mobile internal parts) using equivalent parametric macroelements (EPMs) with a much reduced ...
