AAE 20400: Aeromechanics II

Credits:     3

Contact hours:     3

Instructor:     Professor Yu

Text:     Gere, James M. and Barry J. Goodno, Mechanics of Materials, Cengage Learning, 8th Edition. ISBN 978-1111577735. Supplemental notes furnished by instructor.

Course Description:     This course is to introduce aerospace engineering students to the mechanics of solids concepts of force/stress/equilibrium, deformation/strain/compatibility, and stress/strain material behaviors. These concepts, through examples, are applied to basic aerospace structural components of rods in tension and compression, shafts in torsion, beams in bending and shear, and thin walled vessels under pressure.

Offered:    Fall and Spring

Pre-requisite:    AAE 20300

Co-requisite:    None

Required:    Yes

Student Learning Outcomes:
On completing this course the student shall be able to:

  1. Describe the material behavior of deformable bodies when subjected to loads
  2. Create and use free-body diagrams to compute resultant support forces and moments
  3. Compute internal force and moment distributions
  4. Properly select and use materials based upon their mechanical properties
  5. Compute stresses, strains, deformation and displacements of basic structural components
  6. Predict structural integrity based on the calculations
  7. Apply these ideas for analysis of components related to aerospace applications
