An efficient LDU algorithm for the minimal least squares solution of linear systems
Fernández de Bustos, Igor; García Marina, Vanesa; Urkullu Martín, Gorka; Abasolo, Mikel (Elsevier, 2018-12-15)The minimal least squares solutions is a topic of interest due to the broad range of applications of this problem. Although it can be obtained from other algorithms, such as the Singular Value Decomposition (SVD) or the ... -
An engineering approach for the estimation of slewing bearing stiffness in Wind Turbine Generators
Heras Miguel, Iker ; Aguirrebeitia Celaya, Josu ; Abasolo, Mikel ; Coria Martínez, Ibai (Wiley, 2018-11-30)The stiffness of yaw and pitch slewing bearings has a critical influence on the structural behaviour of Wind Turbine Generators. Thus, it is commonly required by designers for their simulations to estimate deformations ... -
Effect of the geometry of butt-joint implant-supported restorations on the fatigue life of prosthetic screws.
Armentia Sánchez, Mikel; Abasolo Bilbao, Mikel ; Coria Martínez, Ibai ; Sainitier, Nicolas (Elsevier, 2022-03)[EN] STATEMENT OF PROBLEM: Dental implant geometry affects the mechanical performance and fatigue behavior of butt-joint implant-supported restorations. However, failure of the implant component has been generally studied ... -
Efficient assembly of bolted joints under external loads using numerical FEM
Coria Martínez, Ibai ; Martín Lorenzo, Iñigo ; Bouzid, Abdel-Hakim; Heras Miguel, Iker ; Abasolo, Mikel (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 ... -
Fatigue Design of Dental Implant Assemblies: A Nominal Stress Approach
Armentia Sánchez, Mikel; Abasolo Bilbao, Mikel ; Coria Martínez, Ibai ; Albizuri Irigoyen, Joseba (MDPI, 2020-06-03)Fatigue is the most common mechanical failure type in dental implants. ISO 14801 standardizes fatigue testing of dental implants, providing the load-life curve which is most useful for comparing the fatigue behavior of ... -
Fatigue performance of prosthetic screws used in dental implant restorations: Rolled versus cut threads
Armentia Sánchez, Mikel; Abasolo Bilbao, Mikel ; Coria Martínez, Ibai ; Albizuri Irigoyen, Joseba ; Aguirrebeitia Celaya, Josu (Elsevier, 2021-09)Statement of problem. Cold rolling is widely used for screw thread manufacturing in industry but is less common in implant dentistry, where cutting is the preferred manufacturing method. Purpose. The purpose of this in ... -
Friction torque in four contact point slewing bearings: Effect of manufacturing errors and ring stiffness
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 ... -
Friction torque in four-point contact slewing bearings: applicability and limitations of current analytical formulations
Heras Miguel, Iker ; Aguirrebeitia Celaya, Josu ; Abasolo, Mikel ; Plaza González, Jon (Elsevier, 2017-11)The friction torque is a key parameter in the design of slewing bearings. The most challenging issue in its calculation resides in the modelling of rolling element contact mechanics. In this manuscript two models for the ... -
Inspection scheduling based onreliability updating of gas turbinewelded structures
Coro Gallego, Armando ; Abasolo Bilbao, Mikel ; Aguirrebeitia Celaya, Josu ; López de Lacalle Marcaide, Luis Norberto (Sage, 2019-01-28)This article presents a novel methodology for the inspection scheduling of gas turbine welded structures, based on reliability calculations and overhaul findings. The model was based on a probabilistic crack propagation ... -
