Design for a cruciform coupon used for tensile biaxial transverse tests on composite materials
(Elsevier, 2017-06)
This paper focuses on the design of the appropriate geometry for cruciform coupons conceived to be tested under tensile biaxial transverse loads. To this end, Finite Element models were developed and their results were ...

Fitting the fracture curve of concrete as a density function pertaining to the generalized extreme value family
(Elsevier, 2017-09)
The load-displacement (P-δ) curve, recorded during the fracture process of concrete in three-point bending tests, is supposed to depict a fracture phenomenon of statistical character that can be suitably described by a ...

A 2.5D spectral approach to represent acoustic and elastic waveguides interaction on thin slab structures
(Elsevier, 2017)
In this paper, we propose a spectral element method (SEM) to study guided waves in coupled problems involving thin-walled structures and fluid-acoustic cavities. The numerical method is based on the subdomain decomposition ...

Elasto-plastic hardening models adjustment to ferritic, austenitic and austenoferritic Rebar
(Consejo Superior de Investigaciones Científicas (CSIC), 2017)
The elastoplastic behaviour of steel used for structural member fabrication has received attention to facilitate a mechanical-resistant design. New Zealand and South African standards have adopted various theoreti-cal ...

Deformation-diffusion coupled analysis of long-term hydrogen diffusion in nanofilms
(National Technical University of Athens, 2017)
The absorption and desorption of hydrogen in nanomaterials can be characterized by an atomic, deformation-diffusion coupled process with a time scale of the order of seconds to hours. This time scale is beyond the time ...

Probabilistic Flexural Fatigue in Plain and Fiber-Reinforced Concrete
(MDPI AG, 2017-07)
The objective of this work is two-fold. First, we attempt to fit the experimental data on the flexural fatigue of plain and fiber-reinforced concrete with a probabilistic model (Saucedo, Yu, Medeiros, Zhang and Ruiz, Int. ...

Modelo mecano-químico-difusivo fenomenológico de autorreparación: Implementación numérica y simulación con aplicación a materiales estructurales
(2017-10-24)
El concepto de material autorreparable, i.e. material que de forma autónoma tiene la capacidad de recuperar total o parcialmente algunas de sus propiedades, surge de la observación de la naturaleza. Existen multitud de ...

Revisiting the problem of a crack impinging on an interface: A modeling framework for the interaction between the phase field approach for brittle fracture and the interface cohesive zone model
(Elsevier, 2017-07)
The problem of a crack impinging on an interface has been thoroughly investigated in the last three decades due to its important role in the mechanics and physics of solids. In the current investigation, this problem is ...
