This paper addresses a physics based derivation of mode-I and mode-II traction separation relations in the context of cohesive zone modeling of ductile fracture of metallic materials. The formulation is based on the growth of an array of pores idealized as cylinders which are considered as therepresentative volume elements. An upper bound solution is applied for the deformation of the representative volume element and different traction-separation relations are obtained through different assumptions.

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...
Development of a Micromechanics Based Cohesive Zone Model and Application for Ductile Fracture Yalçınkaya, Tuncay; Tandoğan, İzzet Tarık (2019-01-01) In this paper, derivation and implementation of a micromechanically motivated traction separation law for cohesive zone modeling of ductile fracture is discussed. The formulation of the framework is based on the growth of pores in an array of representative volume elements where pores are idealized as cylinders. Two relations are derived under normal and shear loading for mode-I and mixed-mode respectively, based on the upper bound for a perfectly plastic material (Yalcinkaya and Cocks (2015), Yalcinkaya an...
Ductile fracture of metallic materials through micromechanics based cohesive zone elements Tandoğan, İzzet Tarık; Yalçınkaya, Tuncay; Department of Aerospace Engineering (2020-9) Gaining popularity after its coupling with the finite element method, cohesive zone modelling has been used extensively to model fracture, especially in delamination problems. Its constitutive relations, i.e. traction-separation laws, are mostly derived phenomenologically without considering the physical mechanisms of crack initiation and propagation. The approach could also be used for ductile fracture where the micromechanics of the phenomenon is explained by nucleation, growth and coalescence of pores. I...
Evaluation of a new turbulence model for boundary layer flows with pressure gradient Marangoz, Alp; Çıray, Cahit; Department of Aerospace Engineering (2005) In this thesis, a new turbulence model developed previously for channel and flat plate flows is evaluated for flat plate flows with pressure gradient. For this purpose a flow solver, which uses boundary layer equations as the governing equations and Von Karman momentum integral equation for the calculation of skin friction, is developed. It is shown that the error of the new turbulence model, in predicting the velocity profile, is less than 5 % for the flat plate flows without pressure gradient and less tha...
3D Simulation of Dynamic Delamination in Curved Composite Laminates Ata, Tamer Tahir; Çöker, Demirkan (Elsevier BV; 2019-01-01) In this study, dynamic fracture of curved carbon fiber reinforced plastic (CFRP) laminates under quasi-static loading is investigated using explicit three dimensional (3D) finite element method in conjunction with Cohesive Zone Modelling (CZM). The simulations are based on the experimental studies conducted by Tasdemir (2018). Three dimensional finite element models of two different ply architectures (unidirectional and fabric laminate) are generated corresponding to the experimental configurations. The com...
