Estudio de los daños por fatiga en palas de aerogenerador
(Grupo Español de Fractura, 2007)
El presente trabajo tiene como objeto el estudio de los daños detectados en las palas de un aerogenerador de 300 Kw. Estos daños, consistentes en fisuras situadas en la zona de entronque de la raíz, han aparecido en las ...

Estados singulares de tensión en esquinas multimateriales
(Grupo Español de Fractura, 2007)
La unión entre materiales de distinta naturaleza genera puntos críticos en la estructura donde aparecen cambios bruscos en la geometría y propiedades de los materiales (esquinas multimateriales). La teoría de la Elasticidad ...

Prediction of welding residual stresses and displacements by simplified models. Experimental validation
(Elsevier, 2010-03)
Numerical simulations of welding processes are complex and computationally expensive. Several simplificative hypotheses are typically used in the simulations for time saving considerations, some of which have been explored ...

Fatigue crack initiation and damage characterization in Brazilian test specimens for adhesive joints
(Taylor & Francis, 2014)
The present study is focused on the fatigue failure initiation at bimaterial corners by means of a configuration based on the Brazilian disc specimens. These specimens were previously used for the generalized fracture ...

Evaluation of the stiffnesses of the Achilles tendon and soleus from the apparent stiffness of the triceps surae
(SAGE, 2015-01)
The triceps surae plays an important role in the performance of many sports. Although the apparent average mechanical properties of the triceps surae may be a satisfactory parameter for estimating the training level of an ...

Computing stress singularities in transversely isotropic multimaterial corners by means of explicit expressions of the orthonormalized Stroh-eigenvectors
(Elsevier, 2009-01)
Composite materials reinforced by unidirectional long fibers behave macroscopically as homogeneous transversely isotropic linear elastic materials. A general, accurate and computationally efficient procedure for the ...

Influence of the size and depth of a circumferential notch on the impact behavior of streetlights. A passive-safety concept
(Elsevier, 2015-07)
Impact tests on weakened streetlights were carried out using a high energy pendulum. The weakening mechanism consists of a circumferential notch at the base of the streetlight. The objective is twofold: firstly to reduce ...

Representativity of the singular stress state in the failure of adhesively bonded joints between metals and composites
(Elsevier, 2009-09)
Several critical points, where both geometry and material properties change abruptly, arise in an adhesively bonded lap joint between a metallic and a composite material. These critical points, called multimaterial corners ...

Singularity analysis of anisotropic multimaterial corners
(Springer, 2003-01)
Singular stress states induced at the tip of linear elastic multimaterial corners are characterized in terms of the order of stress singularities and angular variation of stresses and displacements. Linear elastic materials ...

A least squares procedure for the evaluation of multiple generalized stress intensity factors at 2D multimaterial corners by BEM
(Elsevier, 2012-03)
Detailed characterization of linear elastic stress states at corners and crack tips requires knowledge of the stress singularity orders, the characteristic angular functions and the generalized stress intensity factors ...
