A new crack-tip element for the logarithmic stress-singularity of Mode-III cracks in spring interfaces
(Springer, 2024-02)
A new crack-tip finite element able to improve the accuracy of Finite Element Method (FEM) solutions for cracks growing along the Winkler-type spring interfaces between linear elastic adherents is proposed. The spring model ...

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 ...

El método de los elementos de contorno aplicado al cálculo de placas apoyadas
(Asociación Española de Ingeniería Mecánica, 1982-12)
Se analiza el problema de placas elásticas apoyadas , sometidas a carga estática mediante una formulación integral obtenida a partir de la des composición de la ecuación biarmónica que rige el comportamiento de dichas ...

CNT-polymer nanocomposites under frictional contact conditions
(Elsevier, 2018-12)
The unique intrinsic physical properties of Carbon NanoTubes (CNTs) suggest that they are ideal fillers for high-performance composites. Although some experimental studies have revealed the potential of these nanoparticles ...

Exploring the impact of graphene oxide on mechanical and durability properties of mortars incorporating demolition waste: micro and nano-pore structure effects
(Consejo Superior de Investigaciones Científicas, 2023-12)
In this study is explored the use of construction and demolition waste as fine aggregate in mortars. The addition of nano-graphene oxide (0.1%wt) has also been evaluated. Tests were conducted to determine their density, ...

Dynamic characterisation of wind turbine towers account for a monopile foundation and different soil conditions
(Taylor & Francis (Routledge), 2017)
The response of wind turbines is induced by dynamic loads such as wind, transient and cyclic loads, and also extreme loads such as earthquakes. Thus, the structural design requires an accurate evaluation of the modal ...

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 ...
