Todorović, Marija (author), Koetsier, M. (author), Simović, Nađa (author), Glišović, Ivan (author), Pavlovic, M. (author)In this paper an efficient procedure for obtaining a cohesive law for Mode I timber fracture (crack opening), based on the Double Cantilever Beam (DCB) tests is given. DCB tests were performed on ten European spruce specimens in order to determine the energy release rate vs crack length (R curves). Two crucial parameters - crack length during...journal article 2023

Moazzami, M. (author), Ayatollahi, M. R. (author), Akhavan-Safar, A. (author), Teixeira De Freitas, S. (author), Poulis, J.A. (author), da Silva, L. F.M. (author)In some industrial applications, adhesive joints are cyclically exposed to a moist environment, where cyclic moisture absorption and desorption can significantly alter the fracture energy of the bonded joints. Most previous studies are based on monotonic aging conditions, while the performance of bonded joints under cyclic aging is not well...journal article 2022

Saleh, M. (author), Tomić, Nataša Z. (author), Marinković, Aleksandar (author), Teixeira De Freitas, S. (author)Two synthesized eco-epoxy components based on TA: (A) glycidyl ether and (B) glycidyl phosphate ester, are used, as a replacement for the Bisphenol A (BPA) based epoxy component, for bonding aluminum (Al) and carbon fiber reinforced polymer (CFRP). Their effect on the mode I fracture toughness (GI) is evaluated by Double Cantilever Beam (DCB)...journal article 2021

Saghafi, Hamed (author), Nikbakht, Ali (author), Mohammadi, Reza (author), Zarouchas, D. (author)The geometrical features of nanofibers, such as nanomat thickness and the diameter of nanofibers, have a significant influence on the toughening behavior of composite laminates. In this study, carbon/epoxy laminates were interleaved with polysulfone (PSF) nanofibrous mats and the effect of the PSF nanomat thickness on the fracture toughness...journal article 2021

Lopes Fernandes, R. (author), Teixeira De Freitas, S. (author), Budzik, Michal K. (author), Poulis, J.A. (author), Benedictus, R. (author)The aim of this study is to investigate the effect of the adherend material on the mode I fracture behaviour of bi-material composite bonded joints. Both single-material (steel-steel and composite-composite) and bi-material (steel-composite) joints bonded with a structural epoxy adhesive are studied. Additionally, two adhesive bondline...journal article 2020

Peters, K.R. (author)The goal of the thesis (executed for Fokker Aerostructures) was to further the understanding of critical parameters in the DCB test method for thermoplastic composites. The influence of fiber bridging, specimen thickness, insert film thickness, crack length and crack opening rate are investigated by means of experimental DCB tests for...master thesis 2017
