Failure analysis of tapered composite structures under tensile loading
Çelik, Ozan; Parnas, Kemal Levend; Department of Mechanical Engineering (2016)
A three dimensional finite element modeling approach is used to evaluate the effects of preliminary design variables on the performance of tapered composite laminates under tensile loading. Hashin failure criteria combined with a progressive failure algorithm is used for in-plane failure mechanisms and cohesive zone method is used for out-of-plane failures. The modeling approach is validated by a comparison with experimental results from literature. The validated model is used to examine various design vari...
Ternary nanocomposites of low density, high density and linear low density polyethylenes with the compatibilizers E-MA-GMA and E-BA-MAh
Işık Coşkunses, Fatma; Yılmazer, Ülkü; Department of Chemical Engineering (2011)
The effects of polyethylene, (PE), type, compatibilizer type and organoclay type on the morphology, rheological, thermal, and mechanical properties of ternary low density polyethylene (LDPE), high density polyethylene (HDPE), and linear low density polyethylene (LLDPE), matrix nanocomposites were investigated in this study. Ethylene – Methyl acrylate – Glycidyl methacrylate terpolymer (E-MAGMA) and Ethylene – Butyl acrylate- Maleic anhydrate terpolymer (E-BA-MAH) were used as the compatibilizers. The organo...
Failure analysis of thick composites
Erdem, Melek Esra; Parnas, Kemal Levend; Department of Mechanical Engineering (2013)
A three-dimensional finite element model is constructed to predict the failure of a hybrid and thick laminate containing bolted joints. The results of the simulation are compared with test results. The simulation comprises two main challenging steps. Firstly, for a realistic model, a 3D model is established with geometric nonlinearities and contact is takeninto account. The laminated composite model is constructed by 3D layered elements. The effect of different number of elements through the thickness is in...
Polyethylene oxide-hydroxyapatite composite and microporous polyethylene oxide-polymethacrylic acid polymer complex preparation and characterization
Banat, Raid M I; Tinçer, Teoman; Department of Chemistry (2002)
The first part of this study covers the crosslinking of polyethylene oxide (PEO) and its composite with calcium hydroxyapatite (HA) and their mechanical, swelling and morphological properties. Sheets of neat PEO (two different molecular weights) and composites of PEO-HA were prepared by compression molding. The composites and PEO thick sheets were crosslinked with exposure of UV- irradiation in presence of acetophenone (AP) for different periods of time. This simple method of crosslinking, UV-irradiation in...
