Different detailed finite element model alternatives are developed to come up with the most reliable finite element model of the sandwich panel, with the actual honeycomb core geometry, to evaluate the existing equivalent continuum models of aluminum honeycomb cores. Finite element models of sandwich panels with effective elastic constants of the honeycomb core are generated based on the existing continuum models of the honeycomb core. The evaluation of the effective elastic constants of honeycomb cores is based on the comparison of the total reaction forces, calculated by both finite element models, on the supported faces of sandwich panels due to different in-plane and out-of-plane uniform input displacements applied to the faces of the panels. The results show that the reliability of the individual in-plane and out-of-plane effective elastic constants of the existing continuum models of the honeycomb cores can be successfully evaluated based on the comparative study.

A procedure to embed fibre Bragg grating strain sensors into GFRP sandwich structures Dawood, T. A.; Shenoi, R. A.; Şahin, Melin (Elsevier BV, 2007-01-01) Embedding FBG strain sensors within a GFRP sandwich composite material allows early detection of internal defects. However, the sensors need to survive the manufacturing process to provide this capability. Vacuum infusion is commonly used to manufacture GFRP sandwich composite materials but, it needs to be modified to accommodate the embedding process. A stage by stage procedure is demonstrated here to embed FBG strain sensors between the skin-core interface of a GFRP sandwich beam specimen using the vacuum...
Micromechanical modelling of carbon nanotube reinforced composite materials with a functionally graded interphase Taç, Vahidullah; Gürses, Ercan (SAGE Publications, 2019-12-01) This paper introduces a new method of determining the mechanical properties of carbon nanotube-polymer composites using a multi-inclusion micromechanical model with functionally graded phases. The nanocomposite was divided into four regions of distinct mechanical properties; the carbon nanotube, the interface, the interphase and bulk polymer. The carbon nanotube and the interface were later combined into one effective fiber using a finite element model. The interphase was modelled in a functionally graded m...
Development of strain monitoring system for glass fiber reinforced composites via embedded electrically conductive pathways Tanabi, Hamed; Erdal Erdoğmuş, Merve (Informa UK Limited, 2019-06-15) Among numerous types of health-monitoring and damage-sensing sensors that can be integrated into composites, electrically conductive sensors offer a simple, cost-effective, and durable option for structural health monitoring in fiber reinforced composites. In this study, a novel approach is introduced to create electrical conductive networks in glass fiber reinforced composites. For this purpose, hollow micro-channels are generated using vaporization of sacrificial components (VaSCs) which are subsequently ...
Non-linear progressive failure analysis of open-hole composite laminates under combined loading Gunel, Murat; Kayran, Altan (SAGE Publications, 2013-05-01) This article presents a finite element-based study of geometrically non-linear progressive failure analysis of open-hole composite laminates, subjected to combined in-plane and out-of-plane loading. Different ply- and constituent-based failure criteria and material property degradation schemes have been coded in Patran command language and a progressive failure analysis code is developed. Progressive failure analyses of the sample composite laminate, with an open-hole, subject to different combined loading ...
Development of a shell finite element for large deformation analysis of laminated composites Yıldız, Tuba; Darendeliler, Haluk; Department of Mechanical Engineering (2008) The objective of the present work is to investigate the behavior of laminated fiber -reinforced polymer matrix composite shell structures under bending load with the help of a modified finite element computer code which was previously developed for the analysis of pseudo-layered single material shells. The laminates are assumed to be orthotropic and the formulation is adapted to first order shear deformation theory. The aim is to determine the large deformation characteristics numerically, and to predict th...
