An engineering approach for the estimation of slewing bearing stiffness in Wind Turbine Generators
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, 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 ... -
Load distribution and friction torque in four-point contact slewing bearings considering manufacturing errors and ring flexibility
Heras, Iker; Aguirrebeitia, Josu ; Abasolo Bilbao, Mikel ; Coria Martínez, Ibai ; Escanciano, Iñigo (Elsevier, 2019-03-16)This work introduces a methodology for the calculation of the load distribution in four-point contact slewing bearings considering ball preload, manufacturing errors and ring flexibility. The model is built by the formulation ... -

Methodology for the assessment of equivalent load for self-lubricating radial spherical plain bearings under combined load
Aguirrebeitia, Josu ; Abasolo, Mikel ; Vallejo Matilla, Javier; Coria Martínez, Ibai ; Heras, Iker (Elsevier, 2016-09-20)... -
On the Use of a Simplified Slip Limit Equation to Predict Screw Self-Loosening of Dental Implants Subjected to External Cycling Loading
Armentia Sánchez, Mikel; Abasolo Bilbao, Mikel ; Coria Martínez, Ibai ; Bouzid, Abdel-Hakim (MDPI, 2020-09-26)Self-loosening of the prosthetic screws is a major mechanical problem affecting roughly 10% of dental implants, according to the literature. This phenomenon may lead to micro-movements that produce crestal bone loss, ... -
Static structural behaviour of wire bearings: comparison with conventional bearings and study of design and operational parameters
Martín Lorenzo, Iñigo ; Heras, Iker; Aguirrebeitia, Josu ; Abasolo Bilbao, Mikel ; Coria Martínez, Ibai (Elsevier, 2018-10-28)In wire bearings the rolling process occurs on raceways machined on steel wires, and the rings are made of light materials such as aluminium. This particular architecture provides both weight and inertia savings, but ... -
