Oktay, Hasan Emre; Göktepe, Serdar; Gürses, Ercan; Department of Civil Engineering (2020-10-23)
In this study, a micromechanical constitutive model for semicrystalline polymers is developed. The proposed model considers interactions among the adjacent regions at the same length scale. The neighborhood information is obtained from the well characterized spherulite morphology of polyethylene. Deformation characteristics of a disk-like spherulite model that has similarities with the considered modeling approach are studied using the finite element method. The model discretizes a disklike spherulite i...

Ti-6Al-4V is one of the most promising alloys for electron beam melting (EBM) of structural parts due to its outstanding properties and its extensive use in the aerospace, automotive, and energy industries. In this study, we report a detailed and systematic micromechanical characterization of additively manufactured Ti-6Al-4V parts produced via EBM. The specimens were characterized by microhardness, nanoindentation, micropillar compression, and microscratch measurements. The results show that the Ti-6Al-4V ...

Micromechanically Motivated Modeling of Semicrystalline Polymers
Oktay, Hasan Emre; Gürses, Ercan; Göktepe, Serdar (2017-09-05)
Semicrystalline polymers (SCPs) are of ever increasing technological importance due to their remarkable toughness, good impact strength, very low gas-permeability, superior wear resistance, and biocompatibility. They have been used in applications such as ballistic plates, model aircraft, liquid and gas containers, plastic bags, piping systems, electrical insulation systems, substrates for flexible electronic devices, and joint implants. Owing to amorphous polymer chain networks and crystalline structures, ...
Micromechanical modelling and two scale simulation of epoxy glass composites with interphases and interfaces
Fleischhauer, Robert; Dal, Hüsnü; Kaliske, Michael (2010-03-26)
Composite systems consisting of glass fibres and epoxy matrix with interphases and interfaces will be considered in the modelling approach. The interphase forms the transition zone between the epoxy matrix and the glass fibre. The interface is the layer between the glass fibre and the surrounding interphase. The macroscopic strength of the composite material is intrinsically related to the bond strength of the polymeric/solid interface and the micromechanical characteristics of the three phases (epoxy, glas...
