The effect of kinematic constraints in the inverse dynamics problem in biomechanics
(Springer, 2016)
The inverse dynamics is a classic problem to be solved in gait analysis. The solution is the vector of joint reactions and driving actions which is essential to perform a kinetic analysis of the human gait. Multibody system ...

Analysis of the influence of stress triaxiality on formability of hole-flanging by single-stage SPIF
(Elsevier, 2019-02)
Traditionally the fracture in sheet metal forming is characterized by the fracture forming limit (FFL) curve typically obtained by using conventional Nakajima tests. This curve is implicitly assumed a material property. ...

Fluid structural analysis of urine flow in a stented ureter
(Hindawi Publishing Corporation, 2016)
Many urologists are currently studying new designs of ureteral stents to improve the quality of their operations and the subsequent recovery of the patient. In order to help during this design process, many computational ...

Experimental Study on the Evaluation of Necking and Fracture Strains in Sheet Metal Forming Processes
(Elsevier, 2013)
In this paper the formability of AA2024-T3 metal sheets is experimentally analyzed. For this purpose, a series of StretchBending and Incremental Sheet Forming (ISF) tests are carried out. The former tests allow determine ...

A fast and non-degenerate scheme for the evaluation of the 3D fundamental solution and its derivatives for fully anisotropic magneto-electro-elastic materials
(Elsevier, 2019-08)
A new expression for the fundamental solution is introduced, presenting three relevant characteristics: (i) it is explicit in terms of the Stroh's eigenvalues, (ii) it remains well-defined when some Stroh's eigenvalues are ...

Aplicación de un modelo micromecánico de crecimiento de grieta de dos umbrales a fatiga por fretting
(Grupo español de fractura, 2012)
El presente trabajo muestra una estimación de la velocidad de crecimiento de grieta por fatiga debido a cargas producidas por fretting. Esto se realiza utilizando el modelo de crecimiento de grieta de dos umbrales, ...

Fretting fatigue life prediction using the extended finite element method
(Grupo español de fractura, 2010)
In this work, fretting fatigue tests available in the literature are modeled using the extended finite element method (XFEM). The aim is to numerically evaluate the stress intensity factors (SIFs) for cracks of different ...
