Abstract

The cardiovascular diseases constitute one of the main causes of death worldwide. One of the main diseases is atherosclerosis, which causes narrowing of the arterial lumen. In order to solve this condition, several treatments have been developed, and Percutaneous Transluminal Coronary [...]

Abstract

A method based on the Refined Zigzag Theory (RZT) to model delamination in composite laminated beam structures is presented. The novelty of this method is the [...]

Abstract

A numerical method based on the Refined Zigzag Theory (RZT) to model delamination in composite laminated plate/shell structures is presented. The originality of [...]

Abstract

The numerical simulation of complex failure modes of composite materials, such as delamination, can be computationally very demanding, as it requires special elements and/or numerical strategies to characterize damage [...]

Abstract

This work shows possibilities and limitations of the refined zigzag theory (RZT) that has been used in different structural (beam, plate and shell) finite elements. The refined zigzag theory can deal with composite laminates, adding only one nodal degree of freedom per spatial [...]

Abstract

The purpose of the present study is the evaluation of the bending-twisting coupling effect in the analysis of the DCB test by means of the analytical determination of the energy release rate of angle-ply laminated composites. The aim is to extend a previous work done by the same [...]

Abstract

Impact is one of most critical stress over a structure, so as it induces a high strain rate on the material. Under low speed transverse impacts in composites, the secuence of material degradation is: intralaminar fracture of the matrix that does not mean a load bearing capacity [...]

Abstract

Este artículo presenta un nuevo procedimiento con el que simular el fallo por delaminación en materiales compuestos. El método propuesto utiliza la teoría de mezclas serie/paralelo, desarrollada por Fernando Rastellini, para la caracterización constitutiva del material compuesto. [...]

Abstract

Although laminated materials have been used for decades, their employment has increased nowadays in the last years as a result of the gained confidence of the industry on these materials. This has provided the scientific community many reasons to dedicate considerable amount of [...]

Abstract

This article is focused on the study of a micro-macro LaTIn based Domain Decomposition Method (LaTIn-DDM) for the prediction of the nonlinear behavior of slender composite structures subjected to bending, buckling and delamination. Previous studies have shown that an adequate selection [...]
