Our graduate admissions process has changed.

As of Sept. 6, 2018, the graduate admissions process has changed. Details about the new process can be found on the graduate admissions page.

The Doctor of Philosophy in Mechanical Engineering is for the student wanting to develop the skills needed to create and discover new knowledge, direct and lead a research group, and otherwise serve as a leader in the process of discovery. The ability to function as a knowledge discovery leader is useful in industry, research labs, and academia. 

The Doctor of Philosophy (Ph.D.) degree requires a minimum of 96 semester credit hours beyond a baccalaureate degree, and a minimum of 64 semester credit hours for a student who has completed a master’s degree.  A student in this program must pass the Qualifying Exams in two of nine areas, according to the Ph.D qualifying examination guidelines found below. A student in this program is expected to pursue a Ph.D. degree, not another degree, in Mechanical Engineering.

96 Hour Ph.D.

Direct 96 Ph.D. (Direct Ph.D. program) Credit Hour Requirements.

The Doctor of Philosophy (Ph.D.) degree requires a minimum of 96 semester credit hours beyond a baccalaureate degree. Direct Ph.D. students shall take a minimum of 33 hours and a maximum of 42 hours of graded coursework. Direct Ph.D. students shall take 3 hours of MEEN 681 (seminar). Direct Ph.D. students shall take a minimum of 51 credit hours of MEEN 691 (research credits). In summary, Graded Courses + Seminar + Research credit hours = 96 credit hours.  For example, a typical Direct Ph.D. plan of study would include a 33 hours of coursework at the 6## level, 3 hours of MEEN 681 (seminar), and 60 hours of MEEN 691 (research).

Within the graded coursework requirement, Direct Ph.D. students must take a minimum of 33 hours of 6## level courses, a maximum of 3 hours of 685, a maximum of 6 hours of 4## coursework, satisfy the Direct Ph.D. math requirement, and satisfy the core course requirement.

Direct Ph.D. Math Requirement

Direct Ph.D. students will take a minimum of 6 hours of 6## level math courses selecting from MEEN 602 - Modeling and Analysis of Mechanical Systems, Math 601– Methods of Applied Mathematics I, Math 603 – Methods of Applied Mathematics II, STAT 601 – Statistical Analysis, or another graduate Mathematics or Statistics course with the approval of the student’s dissertation committee chair.

Core Course Requirement

Two courses from the Core Course list must be taken. 

64 Hour Ph.D. (For those already having a Masters degree)

MEEN 681 – Seminar 2 2
MEEN 691 – Research 44
Total Minimum Semester Credit Hours 64
(beyond M.S. degree)

1 With the approval of student’s dissertation advisor

2 These courses may not include undergraduate courses or two core courses that are required for a master’s degree.  A student in this program who does not have a master’s degree needs eight additional courses and another seminar course, as required for the M.S. degree.

Program Required Portfolio:

Students will prepare a portfolio for assessment. The portfolio will be compiled over the student’s course of study at Texas A&M University. In general, the portfolio will consist of graded materials from classes or research activity that can be evaluated and assessed against the five educational outcomes. The portfolio should be contained in a 3 ring binder or similar.

Educational Outcomes

The assessed educational goals of TAMU MEEN Graduate Program are

A. Graduates will have the ability to apply knowledge of mathematics, science, and engineering,

B. Graduates will have the ability to identify, formulate, and solve engineering problems,

C. Graduates will have the ability to communicate effectively,

D. Graduates will have knowledge of contemporary issues and recognition of the need for lifelong learning, and

E. Graduates will have the ability to use the techniques, skills, and modern engineering tools necessary for engineering practice

It is strongly recommended that students producing a thesis or dissertation as part of their degree requirements use elements of that work or related research papers as the items used for assessment. Students orally defending their thesis/dissertation are encouraged to use that presentation as the assessment media for Educational Outcome C. Also, the Conclusions and Future Work (or similar) section of their thesis/dissertation is likely example work for assessing Educational Outcome D. M. Eng. students will need to build the portfolio over their course of study as appropriate work samples are produced in various classes.  


Ph.D. Qualifying Examinations

The purpose of the Ph.D. Qualifying Exams is to ensure that students pursuing a doctoral degree in Mechanical Engineering have a graduate level understanding of undergraduate Mechanical Engineering fundamentals.

The Department of Mechanical Engineering offers a single qualifying exam covering seven fundamental mechanical engineering topics: controls, design, dynamics, heat transfer, fluid mechanics, thermo-dynamics and solid mechanics. The exam consists of two problems in each topic for a total of 14 problems. Students will select four questions to answer, and have a maximum of four hours to complete the exam. A minimum score of 70 percent is required to pass. 

A student whose highest conferred degree is a master’s or equivalent is allowed a maximum of two attempts to pass the exam. A student whose highest conferred degree is a bachelor’s or equivalent is allowed a maximum of three attempts to pass the exam. Doctoral students are required to make their first attempt to pass the qualifying exam before they have completed 18 semester credit hours, including research hours (MEEN 691). In other words, full-time doctoral students are required to make their first attempt to pass the exam in their second long semester of study (not including summer sessions). Doctoral students are encouraged to take the qualifier earlier in their course of study if they are prepared.

The Ph.D. Qualifying Exam is administered during the second week of the fall and spring semesters every year. Information on exam registration will be emailed to students each semester. Syllabi for the exam areas are taken from undergraduate classes in Mechanical Engineering at Texas A&M. The qualifier subject areas and course syllabi are in the table below. The syllabi are taken from the corresponding class in the fall preceding the exam.

Ph.D qualifier areas and supporting MEEN course(s). The exam committee will use syllabi from the previous fall to select topic areas for examination questions:

An eight-member committee chaired by the Associate Department Head for Graduate Programs prepares the questions/problems for the exam.

Subject Area Syllabus taken from previous fall
Design MEEN 357, MEEN 401, MEEN 402
Dynamics MEEN 225, MEEN 363
Controls MEEN 364
Fluid Mechanics MEEN 344
Heat Transfer MEEN 461
Thermo-dynamics MEEN 315
Solid Mechanics MEEN 225, CVEN 305, MEEN 368

To pass an exam, a student must score 70 percent or higher overall as stated above. A student scoring between 50 and 70 percent may be asked to take a follow-up oral exam. A student scoring 50 percent or lower fails the exam. An exam committee may choose to give a student a conditional pass for which the student must satisfy certain requirements by the end of a given period after the exam, specified by the committee. A doctoral student who fails to pass an exam on his/her final attempt will be given an oral exam in which the student will have a final attempt to pass the exam. 

If a student fails the exam, they must attempt to pass the exam the next time the qualifying exam is offered. A student who does not pass the exam in the allowed number of attempts fails the Ph.D. Qualifying Exam and will not be admitted to Ph.D. candidacy. A doctoral student who fails the Ph.D. Qualifying Exam may (a) switch to a master’s program in Mechanical Engineering (provided that they do not have a master’s degree in Mechanical Engineering from Texas A&M University), (b) pursue a Ph.D. degree in another department at Texas A&M University or another institution, (c) withdraw from the Ph.D. program, or (d) appeal to the departmental Graduate Studies Committee. The Graduate Studies Committee will consider appeals only under extraordinary circumstances, and not as a matter of routine. If the appeal is declined, the student must pursue option (a), (b), or (c) as is allowable and appropriate for that student.

A student must write a registration number that he/she is assigned on his/her exam paper. Nowhere on the exam is a student allowed to write his/her name or student identification number. In addition, students will not be given the names of the members of the committee responsible for writing the exam questions.

The Qualifying Exams will be administered on a Monday. The exam committee will complete the grading of the written exams and any follow-up oral exams, and will report the results of the exams to the Associate Department Head for Graduate Programs in an e-mail by Friday of that week. However, under extenuating circumstances, such as conflicts in scheduling of oral exams, the exam committee may report the results of the exams by the following Friday. The graduate program office will inform students of the results of the exams in writing.
