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 ...
An expert system based material selection approach to manufacturing

İpek, Mümtaz; Selvi, İhsan Hakan; Fındık, Fehim; Torkul, Orhan; Cedimoğlu, İsmail Hakkı (ELSEVIER SCI LTD, 2013)

Selection of proper materials for a diverse mechanism is one of the hardest tasks in the design and product improvements in various industrial applications. Materials play a vital and important function during the entire ...
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 ...
EFFECT OF VIRTUAL WELDING SIMULATOR ON TIG WELDING TRAINING

Öz, Cemil; Serttaş, Soydan; Ayar, Kayhan; Fındık, Fehim (INT COUNCIL MATERIALS EDUCATION, 2015)

The objective of the study is to analyze the contribution of our simulator to assisting trainees in developing their TIG (tungsten inert gas) welding skills. With use of the developed virtual welding simulator, three-dimensional ...
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 ...
Surface spin disorder and spin-glass-like behaviour in manganese-substituted cobalt ferrite nanoparticles

Kazan, Serap; Topkaya, R; Akman, O; Aktas, B; Durmus, Z; Baykal, A (SPRINGER, 2012)

Manganese-substituted cobalt ferrite nanoparticles coated with triethylene glycol (TREG) have been prepared by the glycothermal reaction. The effect of Mn substitution and coating on temperature-dependent magnetic properties ...
