Modelling of Damage and Failure in Multi-Phase Microstructures through Phase Field Fracture Erdoğan, Can; Yalçınkaya, Tuncay (2026-01-01) Multi-phase materials, such as fiber reinforced composites, metal matrix composites, or dual-phase steels, contain two or more contrasting phases within their microstructures. The coexistence of hard/brittle phases with so...
An adaptive phase field model for high cycle fatigue analysis across specimen geometries Chen, Guangxu; Erdoğan, CAN; Yalçınkaya, Tuncay; Wang, Xianqiao; Tang, Keke (2025-12-01) High cycle fatigue behavior of components with notches and cracks, which are common in engineering applications, is significantly influenced by geometrical size effect and complicates accurate fatigue life prediction. Trad...
Post heat treatment optimization of cold spray additive manufactured Inconel 718 Karakas, Aptullah; Ataee, Arash; Rathi, Amit; Fenercioglu, Tevfik Ozan; Erdoğan, Can; Yalçınkaya, Tuncay (2025-12-01) The cold spray technique has recently emerged as an additive manufacturing method for producing free-standing parts, in addition to its use in repair and coating applications. Manufacturing relatively hard alloys such as I...
Analysis of the size effect in the nanoscratching process of single crystalline and polycrystalline materials Günay, Enes; Yalçınkaya, Tuncay (2025-12-01) In tribology, nanoscratch testing is used to evaluate the mechanical and tribological properties of materials by employing a nanoscale indenter. At this scale, size-dependent plasticity effects, particularly those related ...
Explicit Crystal Plasticity Modeling of Texture Evolution in Nonlinear Twist Extrusion Şimşek, Ülke; Miyamoto, Hiroyuki; Yalçınkaya, Tuncay (2025-11-01) The Nonlinear Twist Extrusion (NLTE) method, a novel severe plastic deformation (SPD) technique, aims to enhance grain refinement and achieve a more uniform plastic strain distribution. Grain size and its uniform distribut...
Microstructure Based Analysis of Plasticity and Failure of Dual Phase Steels Çelikses, Eren; Yelek, İbrahim; Özdemir, Merthan; Yalçınkaya, Tuncay (2025-07-01)
Stress state dependent phase field modeling of ductile fracture Erdoğan, Can; Yalçınkaya, Tuncay (2025-07-01)
Stress state dependent phase field modeling of ductile fracture Yücel, Iremnaz; Erdoğan, Can; Yalçınkaya, Tuncay (2025-07-01)
Multi-scale Modeling of Polycrystal Turbine Disk and Single Crystal Turbine Blade with Orientation Deviations Under Cyclic Operational Loading Açar, Sadık Sefa; Bulut, Orhun; Yalçınkaya, Tuncay (2025-06-02)
Stress state dependent phase field modeling of ductile fracture Yücel, İsmail; Erdoğan, Can; Yalçınkaya, Tuncay (2025-01-01) The simulation of ductile fracture is commonly performed with uncoupled damage modeling techniques using the finite element method. In this approach, damage evolution is defined by a failure criterion, and the failure itse...
