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 interdisciplinary 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 for providing an interdisciplinary engineering education. We strive to prepare our graduates to succeed in advanced graduate or professional study, industry, and government. In these activities, our alumni will:
- Apply fundamentals of engineering mechanics and related areas of applied science to define, model, and solve a wide range of engineering problems.
- Apply fundamental mathematical and scientific principles, as well as computational and experimental techniques, to the demands of engineering and scientific practice.
- Function on and lead teams that engage in new areas of research and development in engineering, particularly those that cross the boundaries of traditional disciplines.
- Maintain high productivity and high ethical standards.
- Continually enhance their knowledge throughout their careers.
- Communicate effectively to a broad range of audiences.
These educational objectives are supported by a curriculum that provides its graduates with:
- an ability to apply fundamental knowledge of mathematics, science, and engineering
- an ability to design and conduct mechanics experiments
- an ability to analyze and interpret experimental and computational mechanics data
- an ability to design a system, component, or process to meet desired needs by synergistically combining mechanics of materials, fluid mechanics, and dynamics, when necessary
- an ability to effectively function as the leader, or member, of a multi-disciplinary team
- an ability to identify, formulate, and solve engineering problems involving mechanics of materials, fluid mechanics, and/or dynamics
- an understanding of professional and ethical responsibility
- an ability to communicate effectively – orally, graphically, and in writing
- the broad education necessary to understand the impact of engineering solutions on society and the environment
- a recognition of the need for, and an ability to engage in, life-long learning and accomplishment
- a knowledge of contemporary issues (e.g., social, political, technical, economic, etc.)
- a fundamental understanding that will enable the appropriate use and development of the techniques, skills, and modern engineering tools necessary for engineering practice
- a recognition of the importance of safety in phases of engineering design and practice
A total of 12 credit hours of technical electives and 6 credit hours of senior design give the student freedom to develop individually tailored programs of concentrated study. The department has emphasis areas in Biomechanics, Engineering physics, Fluid mechanics, Motions, or Solid mechanics. Exposure to the design process exists throughout the curriculum, culminating in a senior level capstone design course. The department offers official university degree options in Biomechanics and Engineering Physics. The graduation checksheets for all degree options are available at http://www.esm.vt.edu/curriculum_checksheet.php.
The Cooperative Education Program is available to qualified candidates at undergraduate and graduate levels.
Undergraduate courses in engineering science and mechanics are taught on a service basis for all engineering curricula. A minor in engineering science & 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. Students with an interest in this program should contact the department for additional information.
