Three dimensional finite element study of the behaviour and failure mechanism of non-crimp fabric composites under in-plane compression
(Elsevier, 2016-08)
The compressive behaviour and the mechanism responsible for failure of a [0,90]n non-crimp fabric (NCF) laminate are studied using a 3D finite element (FE) model of the representative unit cell at the mesoscopic scale. The ...

Effect of Cohesive Properties on Low-Velocity Impact Simulations of Woven Composite Shells
(MDPI, 2023-06)
The effect of the interface stiffness and interface strength on the low-velocity impact response of woven-fabric semicylindrical composite shells is studied using finite element (FE) models generated with continuum shell ...

On the 3D extension of failure models for adhesive joints under mixed-mode fracture conditions: LEBIM and CZM
(Elsevier, 2019-04)
Interface models for triggering damage events have been extensively used in many engineering applications due to their inherent versatility and relatively simple numerical implementations. Usually, the non-linear behavior ...

A direct pedestrian-structure interaction model to characterize the human induced vibrations on slender footbridges
(Consejo Superior de Investigaciones Científicas, CSIC: Instituto Eduardo Torroja, 2014)
Although the scientific community had knowledge of the human induced vibration problems in structures since the end of the 19th century, it was not until the occurrence of the vibration phenomenon happened in the Millennium ...

A crowd-structure interaction model to analyze the lateral lock-in phenomenon on footbridges
(WIT Press, 2018)
In this paper a simplified biomechanical crowd-structure interaction model is proposed and validated in order to analyse the lateral lock-in phenomenon on real footbridges. The proposed crowd-structure interaction model ...

Numerical treatment of thick shells with holes
(1979)
A Boundary Integral Equation Method (B.I.E.M.)formulation is presented. After a general situation of the method among other usual numerical ones, the possibilities of discretization are developed. As this is done only in ...

Crack onset and growth at the fibre–matrix interface under a remote biaxial transverse load. Application of a coupled stress and energy criterion
(Elsevier, 2012-09-01)
A theoretical model for prediction of the critical load generating a crack onset at the fibrematrix interface under a remote biaxial transverse load is presented. In particular, this work is focused on the tension dominated ...

Cálculo del término no singular de tensiones en una grieta 3D mediante una integral independiente del dominio
(Grupo Español de Fractura, 2006)
El término no singular de tensiones, denominado también “T-stress”, es el término asociado al autovalor λ =1 en la serie desarrollada por Williams (1957) para el campo de tensiones lineal elástico cercano al vértice de ...
