Micromechanical cohesive zone relations for ductile fracture
Yalçınkaya, Tuncay (Elsevier BV; 2016-06-24)
This paper addresses the derivation of a micromechanically motivated incremental mixed-mode traction separation law in the context of cohesive zone modeling of crack propagation in ductile metallic materials. The formulation is based on the growth of an array of pores idealized as cylinders which are considered as the representative volume elements. An upper bound solution is applied for the deformation of the representative volume element and different incremental traction-separation relations are obtained...
Micromechanical characterization of metallic glass — crystalline nanocomposite coatings
Abboud, Mohammad; Özerinç, Sezer; Kalay, Yunus Eren; Department of Micro and Nanotechnology (2018)
Amorphous/crystalline nanolayers provide an effective model system to study the mechanical behavior and size effects of metallic glasses and crystalline metals in confined geometries. They also provide an advantageous structure for improving the ductility of amorphous metals while maintaining their outstanding strength. Combination of high strength and ductility make these nanocomposites promising materials as wear resistant coatings. The structure-property relationship in Amorphous/Crystalline nanolayers c...
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...

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 ...
