On the combination of geometrically nonlinear models and substructuring for multibody simulation of wind turbine blades
(ASME, 2022-11)
This study develops a geometrically nonlinear model of a wind turbine blade utilizing finite strain theory for the calculation of elastic forces. The model is based on the floating frame of reference (FFR) formulation, ...

Experimental and numerical analysis of fatigue cracks emanating from internal defects in Ti6Al4V SLM
(Elsevier, 2021)
In the present work a series of fatigue tests on Ti6Al4V SLM parts are analyzed via both SEM and confocal microscopy. On the one hand, fracture surfaces are studied, and a common pattern is found, formed by a series of ...

Study of the Contribution of Nonlinear Normal Modes (NNMs) in Large Amplitude Oscillations of Simply Supported Beams
(Elsevier Ltd, 2017)
This paper focuses on the Nonlinear Normal Modes of simply supported beams with unrestrained axial displacements. Two different configurations are considered, depending on whether longitudinal displacements are allowed at ...

Preliminary investigation on homogenization of the thickness distribution in hole-flanging by SPIF
(Elsevier, 2017-06)
A drawback of the hole-flanging process by single-stage SPIF is the non-uniform thickness obtained along the flange. Multi-stage strategies have been used to improve it, however they increase notably the manufacturing time. ...

Predicción de vida en componentes con gradientes de tensiones: entallas y fatiga por fretting
(Grupo español de fractura, 2009)
La fatiga en componentes con entalla y la fatiga por fretting son dos fenómenos diferentes pero tienen en común la existencia de un gradiente de tensiones. En estos casos la predicción de la vida a fatiga se suele realizar ...
