PhD Program

Innovation in product design and manufacturing has become a major driver for industrial competitiveness and profitability in recent years. As enabling technologies become more easily accessible, engineers are faced with increasing demands for designing and producing more complex mechanical devices to serve the needs of the society. Next generation engineering products will be ‘smart’ with many functionalities; they will be made of new materials; they will increase energy efficiency and reduce environmental impact; they will vary in size from nano to mega scales; and they will be more closely integrated with information processing systems. Also as mechanical systems are becoming increasingly complex to analyse and expensive to experiment, more emphasis will have to be placed on computer aided analysis, design, verification and manufacturing. Our research program in mechanical engineering responds to these trends and focuses on basic research related to materials science and process engineering, product design, and information integrated manufacturing processes. In doing so applications to different physical processes are studied (e.g. energy systems, bioengineering, metal forming, polymer processing, discrete part manufacturing to name a few).

Degree Requirements

Students can apply to the Ph.D. programs with a B.S. or M.S. degree. The Ph.D. degree requires successful completion of 14 courses within 3 years and take the Qualifying Examination within 7th semester at latest beyond the B.S. degree and 7 courses within 2 years and take the Qualifying Examination within 5th semester at latest beyond the M.S. degree. In addition to the credit courses, students must complete the non-credit courses; ; KOLT 500: KOLT Graduate Teaching Assistant Training, MECH 590: Seminar, ENGL 500: Academic Writing, ETHR 500: Scientific Research Methods and Research and Publication Ethics, TEAC 500: Teaching Experience and MECH 695: PhD Thesis Course.

Qualifier Exam Rules

REGULATIONS FOR PhD QUALIFIER EXAM IN MECHANICAL ENGINEERING

  • The Committee for the PhD Qualifier Exam schedules and evaluates the PhD Qualifying exam twice a year.
  • The following faculty members work in the committee:
    • Demircan Canadinç
    • Mehmet Sayar
    • Erdem Alaca
    • İpek Başdoğan
    • Murat Sözer
  • The time of the exam is advised to the student by the academic advisor of the student.
  • The student must take and pass the exam BEFORE THE END OF THE FIFTH SEMESTER.
  • This exam has two parts: written and oral.
  • If the student fails in the written part of the first exam, a second exam (both parts) is offered.
  • If the student fails in the oral part of the first exam, only the oral exam of the second exam is offered.
  • The written part has problems covered in the following undergraduate courses (along with the faculty members teaching them currently):
    • MATH 203 Mehmet Sayar
    • MATH 204 Demircan Canadinç
    • MECH 201 Murat Sözer
    • MECH 202 Erdem Alaca
    • MECH 204 Arif Karabeyoğlu
    • MECH 206 İsmail Lazoğlu
    • MECH 301 Metin Muradoğlu
    • MECH 302 İpek Başdoğan
    • MECH 303 Erdem Alaca
    • MECH 304 Çağatay Başdoğan
    • MECH 306 Melis Şerefoğlu
  • The students will solve a total of six problems in the written part: one from MATH 203, one from MATH 204, and any four from MECH 201 – 306 listed above.
  • Each problem in the written part is 20 points; and the passing grade is 70/120. The exam result is announced as Pass/Fail.
  • If the student passes from the written part, then an oral exam is offered within a week. In this part, a committee 5 jury members (including the student’s academic advisor and at least 2 non-KU) assigns a technical article related to the student’s research area (but not published by the same group) for the student to read and prepare a presentation about it for a maximum of 30 minutes. In the next 30 minutes, the student is expected to answer questions about that paper.

Time of the exam: The written part is held on the second Friday of each semester (Fall and Spring); and the oral exam is held on the third Friday of each semester. The committee has the right to change this schedule at the beginning of each semester.
