In silico dynamic characterization of the femur: Physiological versus mechanical boundary conditions
(Elsevier, 2018-08)
It is established that bone tissue adapts and responds to mechanical loading. Several studies have suggested an existence of positive influence of vibration on the bone mass maintenance. Thus, some bone regeneration therapies ...

A time domain analysis of train induced vibrations
(Techno-Press, 2012)
This paper is intended to show the robustness and capabilities of a coupled Boundary Element-Finite Element technique for the analysis of vibrations generated by high-speed trains under different geometrical, mechanical ...

Effect of the end cross beams on the railway induced vibrations of short girder bridges
(Elsevier, 2019-12-15)
This work is devoted to the analysis of the railway-induced vertical vibrations of simply-supported double track bridges composed by pre-stressed concrete girder decks. Despite the low torsional stiffness that this particular ...

On the formulation of a BEM in the Bézier–Bernstein space for the solution of Helmholtz equation
(Elsevier, 2019-10)
This paper proposes a novel boundary element approach formulated on the Bézier-Bernstein basis to yield a geometry-independent field approximation. The proposed method is geometrically based on both computer aid design ...

Numerical study of the inter-fibre failure under biaxial loads
(Elsevier, 2011)
The inter-fibre/matrix failure under transverse tension has already been the object of several micromechanical studies by the authors, for single fibre case or dilute packing. These studies have made it possible to understand ...

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. ...

Damage localization and quantification in beams from slope discontinuities in static deflections
(KoreaScience, 2018)
This paper presents a flexibility based method for damage identification from static measurements in beam-type structures. The response of the beam at the Damaged State is decomposed into the response at the Reference State ...

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 ...
