Numerical implementation and analysis of a porous plasticity model for ductile damage prediction
Erdoğan, Can; Yalçınkaya, Tuncay; Department of Aerospace Engineering (2021-1-27)
Ductile damage and fracture are known to be driven by the microvoid nucleation, growth, and coalescence. Porous micromechanical description of the ductile metals led to many phenomenological material models, which are used to predict the damage and fracture in engineering structures. In this thesis, the assessment of a rateindependent porous plasticity model is done through the representative volume element (RVE) calculations. The model is based on the formalism presented in [1] which is implemented as a us...
Joint analysis in the rock settlements of Cappadocia, Turkey
Sevindi, Gökhan; Toprak, Vedat; Department of Geological Engineering (2003)
This thesis attempts to seek a relationship between the joints developed in the ignimbrites and the rock settlements carved in the same units. Orientation of rooms, directions of walls and joints (both in the rooms and in the field) are input data used in the study. Two sites in Cappadocia (Eskigümüşler and Çanlikilise) are selected to investigate the relationship. Both sites are carved within the same ignimbrite (Kizilkaya) and are located on the south-southeastern slopes of the ignimbrite scarp. Measureme...
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...
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...
Adsorption and dissociation of PH3 on SiGe(100) (2x1) surface
Turkmenoglu, Mustafa; Katırcıoğlu, Şenay (World Scientific Pub Co Pte Lt, 2008-06-01)
The most stable structures for the adsorption and dissociation of phosphine (PH3) on SiGe(100) (2 x 1) surface have been investigated by relative total energy calculations based on density functional theory. According to the optimization calculations, PH3 is adsorbed on the Si (down) and Ge (down) site of the Ge-Si and Ge-Ge dimers on SiGe surface, respectively. The PH2 and H products have been found to be thermodynamically favored in the dissociation path of PH3 on SiGe surface when the system is thermally...
