Micro Damage and Cracking in Fibre Reinforced Composites by a Novel Hybrid Numerical Technique
(American Institute of Physics Inc., 2020-11-26)
The prediction of failure mechanisms in fibre-reinforced composite materials is of great importance for the design of composite engineering applications. With the aim of providing a tool able to predict and explain the ...

Modeling fracture of multidirectional thin-ply laminates using an anisotropic phase field formulation at the macro-scale
(Elsevier, 2023-06)
An equivalent single layer approach to model fracture events of multidirectional balanced thin-ply laminates via the use of the Phase Field method is explored. The inherent anisotropic nature of a multidirectional laminate ...

Empirical flexural behaviour approach of adobe masonry
(Historical and Mansory Structures, 2012)
Adobe masonry is one of the most widespread low cost material used for housing in the world. Unfortunately, it shows very low mechanical strength and it is mainly used in seismic. Therefore, there is a requirement for ...

Utilización de la técnica de los elementos discretos de tomografía sísmica
(Asociación Española de Ingeniería Mecánica, 1986)
La tomografía es un sistema de obtención de imágenes internas de sólidos a los que no se tiene acceso directo. Esta técnica ha sido ya de enorme fecundidad en el campo del diagnostico médico. Hoy día el sistema sigue ...

Review of finite element model updating methods for structural applications
(Elsevier, 2022)
At the time of designing structures up to date, the density and magnitude of the load have increased, and the requirements for regulation have also become more stringent. To ensure the essential requirements, especially ...

Calibration of a total strain crack model for adobe masonry based on compression and diagonal compression tests
(Elsevier, 2022)
Although it has good compressive behavior, adobe masonry is classified as a quasi-brittle material mainly due to its relative low tensile strength and softening behavior after the peak tensile strength. The behavior, plus ...

An accurate treatment of non-homogeneous boundary conditions for development of the BEM
(Elsevier, 2020-07)
This paper proposes an enhancement of the treatment of non-homogeneous boundary conditions to improve the boundary element method (BEM) formulation. The standard formulation is modified by introducing the boundary conditions ...

Three dimensional finite element model of a non-crimp fabric laminated using geometrically straight tows with crimped material properties
(AEMAC (Asociación Española de Materiales Compuestos), 2009)
The compressive failure of a [0,90]n non-crimp fabric laminate is studied using a 3D finite element model of the representative unit cell at mesoscopic scale. In previous analyses, tow elements coordinate systems were ...
