A simple approach for multiaxial fatigue damage prediction based on FEM post-processing

Kocabıçak, Ümit; Fırat, Mehmet (ELSEVIER SCI LTD, 2004)

A simple methodology to predict crack initiation life is described in the fatigue damage assessment of metallic structures typically used in ground vehicle industry. A phenomenological constitutive model is integrated with ...
A switchable approach to large object allocation in real-time Java

Şahin, Veysel Harun; Kocabıçak, Ümit (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2016)

Over the last 20 years object-oriented programming languages and managed run-times like Java have been very popular because of their software engineering benefits. Despite their popularity in many application areas, they ...
Analytical durability modeling and evaluation - complementary techniques for physical testing of automotive components

Fırat, Mehmet; Kocabıçak, Ümit (PERGAMON-ELSEVIER SCIENCE LTD, 2004)

As a result of the commercial pressure new methods of durability evaluation have to be explored, automotive suppliers are now being asked to develop new components and subsystems in shorter times and using fewer physical ...
Comparison of the developed thermal stresses in Al2O3-SG, ZrO2-12%Si+Al and ZrO2-SG coating systems subjected to thermal loading

Kocabıçak, Ümit; Mimaroğlu, Abdullah; Sarıkaya, Özkan; Mete, Osman Hamdi (ELSEVIER SCI LTD, 1999)

In this investigation, thermal and structure finite element analysis has been employed to analyse the thermal stresses developed in Al2O3-SG, ZrO2-12%Si + Al and ZrO2-SG coatings subjected to thermal loading. Systems with ...
Improving estimation of body lengths using extended Kalman Filter for squat movement

Eski, Hüseyin; Kocabıçak, Ümit; Gelen, Ertuğrul (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2019)

Modeling and analyzing of human movements has become easier with the development of sensor technologies. Human movements can be modeled using image processing software with depth and motion sensors in 3D. Measurement errors ...
Influence of porosity characteristics in MgO.ZrO2-GG coating subjected to thermal loading

Mimaroğlu, Abdullah; Kocabıçak, Ümit (ELSEVIER SCI LTD, 1997)

In this investigation, coupled (thermal and structure) finite-element analysis has been employed to analyse the influences of porosity volume, size and distribution in MgO.ZrO2-GG coating subjected to thermal loading. ...
Numerical analysis of wheel cornering fatigue tests

Kocabıçak, Ümit; Fırat, Mehmet (PERGAMON-ELSEVIER SCIENCE LTD, 2001)

In automotive engineering, the wheels are one of the most critical components and their function is of vital importance n human safety. The cornering fatigue test is one of the traditional durability tests for wheel prototype ...
Region based interpolation error expansion algorithm for reversible image watermarking

Yüzkollar, Can; Kocabıçak, Ümit (ELSEVIER, 2015)

In this paper, we propose a new reversible image watermarking method based on interpolation-error expansion called region based interpolation error expansion (RBIEE). We improved Thodi's prediction error expansion (PEE) ...
Risk analysis of lung cancer and effects of stress level on cancer risk through neuro-fuzzy model

Atinc Yilmaz; Seckin Ari; Kocabıçak, Ümit (ELSEVIER IRELAND LTD, 2016)

A significant number of people pass away due to limited medical resources for the battle with cancer. Fatal cases can be reduced by using the computational techniques in the medical and health system. If the cancer is ...
Stamping process design using FEA in conjunction with orthogonal regression

Fırat, Mehmet; Mete, Osman Hamdi; Kocabıçak, Ümit; Özsoy, Murat (Elsevier Science BV, 2010)

A process design technique is presented for the formability assessment of sheet metal stamping parts and feasibility analysis of process conditions. The proposed approach is based on numerical simulation of stamping processes ...
