Description

For one/two-semester introductory courses in vibration for undergraduates in Mechanical Engineering, Civil Engineering, Aerospace Engineering and Mechanics

¿

Serving as both a text and reference manual, Engineering Vibration, 4e, connects traditional design-oriented topics, the introduction of modal analysis, and the use of MATLAB, Mathcad, or Mathematica. The author provides an unequaled combination of the study of conventional vibration with the use of vibration design, computation, analysis and testing in various engineering applications.

¿

Teaching and Learning Experience

To provide a better teaching and learning experience, for both instructors and students, this program will:

  • Apply Theory and/or Research: An unequaled combination of the study of conventional vibration with the use of vibration design, computation, analysis and testing in various engineering applications.
  • Prepare Students for their Career: Integrated computational software packages provide students with skills required by industry.
