Overview
- Mechanics is a fundamental area of science and engineering. It is an exciting, expanding field of learning with its roots grounded in the laws of motion formulated by Newton and the principles governing the behavior of solids and fluids, branching out in modern times into pertinent interdisciplinary high technology fields such as new engineering materials (adhesives, composites, polymers, light metals), biomechanics, transportation, wind engineering, and vehicular structures. Although the problems to which they are applied may change, the basic principles of mechanics remain current and relevant.
- The Department of Engineering Science and Mechanics has a rich tradition at Virginia Tech for providing a strong interdisciplinary engineering education. The undergraduate program educational objectives are:
- To produce graduates with a broad educational background in engineering science and mechanics.
- To produce graduates with an interdisciplinary background with a strong base of fundamental knowledge of the engineering sciences, physical sciences, applied mathematics, capable of discovering solutions to engineering problems appropriate to the needs of society and technology.
- To produce graduates employable in a modern engineering environment with a commitment to lifelong learning and achievement.
- These educational objectives are supported by a curriculum that seeks to have its graduates achieve the following program outcomes:
- Possession of a strong foundation in the basic and engineering sciences, mathematics, and fundamentals of engineering.
- Understanding of first principles in the traditional areas of mechanics: solid mechanics and materials, fluid mechanics, and dynamics.
- A capacity to apply engineering fundamentals and first principles of mechanics to a wide variety of engineering problems.
- Knowledge and experience in analytical, computational, and experimental methods, and an ability to critically evaluate these approaches for use in a given situation.
- The ability to combine various areas of mechanics and other disciplines.
- Exposure to the design process throughout the undergraduate curriculum, including capstone design exercises in which both group and individual efforts are involved.
- Exposure to a curriculum that possesses flexibility to the degree that the student might concentrate in one of the traditional areas of mechanics, in a discipline such as biomechanics, in a discipline centered outside the ESM department; or the student might opt to gain a more comprehensive general background in engineering science and mechanics.
- Effective written and oral communication skills.
- A sense of social, ethical, and human responsibilities, including a historical perspective of the impact of technology.
- The recognition that engineering is a lifelong combination of education and achievement.
- A total of 12 credit hours of technical electives, 6 credit hours of senior design and project and 8 credit hours of free electives give the student freedom to develop individually tailored programs of concentrated study. Students take courses in basic engineering sciences such as statics, dynamics, deformable bodies, and fluid mechanics, followed by applications oriented courses in solids, fluids, dynamics, and experimental and computational methods. Exposure to the design process exists throughout the curriculum, culminating in a senior level capstone design course.
- Undergraduate courses in engineering science and mechanics are taught on a service basis for all engineering curricula. A minor in mechanics is available for engineering students. The department offers graduate programs leading to M.S. (thesis and non-thesis option), M.Eng., and Ph.D. The department also participates in the Five Year Bachelor's/Master's Program.
- Biomechanics Option: An option in Biomechanics is available for students in engineering. Specific details of course requirements for this option may be obtained by contacting the department.
- The Cooperative Education Program is available to qualified candidates at undergraduate and graduate levels.
- Students majoring in Engineering Science and Mechanics who are residents of Delaware, Maryland, South Carolina, and West Virginia may be eligible for the Academic Common Market, a program whereby residents of these states are eligible for Virginia in-state tuition. Contact the Office of Undergraduate Admissions for information.
- A total of 136 credits are required for the ESM degree.
Areas of Concentration
-
The student may use the technical electives, free electives, and the
senior design and project to develop individually tailored programs of
concentrated study in one of the following areas:
- Biomechanics
- Fluid mechanics
- Motion
- Solid mechanics/materials
- In cases where a student plans to go on to medical school, entrance requirements can be satisfied. Students who do not want to complete the entire biomechanics sequence (BIOL 2405-2406, ESM 1114, 4105-4106, 4204, 4574, 5405-5406) may study a smaller number of courses in this field.
