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 ...
A Metamodeling Technique for Variable Geometry Trusses Design via Equivalent Parametric Macroelements
(ASME, 2009-09-03)
A metamodeling methodology is applied to reduce the large computational cost required in the design of variable geometry trusses (VGTs). Using this methodology, submodels of finite elements within a complete FE model of ...
Influence of the Geometrical Design on Ball and Crossed Roller Wire Race Bearing Behavior under Axial Load
(Elsevier, 2020-12-05)
Wire bearings are becoming popular these days in applications such as defence, robotics, medical devices or shipping industry. They provide weight and inertia reductions, good shock load and vibration absorbing capacity, ...
Analysis of a reversible five-point bending configuration based on a novel two-sense support
(Elsevier, 2015-05)
A novel two-sense support for flexural tests has been designed and manufactured in Ikerlan. The aim of this support is to do two-sense bending fatigue tests. In order to reduce the displacement corresponding to a given ...
Analysis of the regimes in the scanner-based laser hardening process
(Elsevier, 2016-10-10)
Laser hardening is becoming a consolidated process in different industrial sectors such as the automotive industry or in the die and mold industry. The key to ensure the success in this process is to control the surface ...
Analytical and numerical approach of an End Notched Flexure test configuration with an inserted roller for promoting mixed mode I/II
(Elsevier, 2015-06-22)
A test configuration for studying mixed-mode is analyzed analytically and numerically. It is based on the End Notched Flexure test, inserting a roller in the cracked part in order to promote mixed mode I/II. The analytical ...
Effect of microwave heating damage on the electrical, thermal and mechanical properties of fibre-reinforced cement mortars
(Elsevier, 2018)
Nowadays, refurbishing of existing structures has gained interest in order to reduce both the construction materials used and the construction and demolition waste production. For that purpose, there are several methods ...
A multidisciplinary sustainability index to assess transport in urban areas: a case study of Donostia- San Sebastian, Spain
(Routledge, Taylor & Francis Group, 2017-03-23)
The management of urban transportation systems represents one of the most
formidable challenges for local government that generates several problems related to
the well-being and the comfort of the public that commute ...
Bond between steel reinforcement bars and electric arc furnace slag concrete
(Springer, 2017-04-21)
This paper deals with the bond between steel reinforcement and recycled aggregate concrete, including Electric arc furnace (EAF) slag as full replacement of natural coarse aggregates. Pull-out tests were carried out according ...
