Relationship to Student Outcomes
No student outcomes specified.
Course Learning Outcomes. Students will:

1. Execute the most common experiments for the determination of the mechanical properties of materials and structures

2. Gain significant familiarity with the universal testing frame

3. Be exposed to the programming language Labview

4. Prepare samples for mechanical experiments

5. Learn modern techniques of local strain measurement, including strain gages and strain mapping

6. Observe and explain the different mechanical behavior of the different classes of materials (metals, polymers, ceramics and composites)

7. Learn about stress intensification around holes and its effect on design

8. Learn how to write well-prepared lab reports

Prerequisites by Topic

Mechanics of materials, Basic materials science

Lecture Topics:
  • Introduction to the universal testing frame: hardware and software (Labview) aspects (1 week)
  • Tension test on metals, polymers, and ceramics (3 weeks)
  • Local strain measurement techniques:
    • Strain gages (1 week)
    • Strain mapping (1 week)
  • Bending test: 3-point bending, 4-point bending (2 weeks)
  • Compression test: yielding and buckling (1 week)
  • Stress intensification test (1 week)
Class Schedule:

Meets for 1 hour of laboratory each week for 10 weeks.

Computer Usage:

Basic computer skills. Students will learn the fundamentals of Labview.

Laboratory Projects:

Students will be divided in groups; each group will perform 6-7 experiments at the conclusion of which each student will individually prepare lab reports. Reports will contain (i) abstract, (ii) motivation for the experiment and expected outcome, (iii) presentation of the collected data, (iv) data analysis and interpretation of results, and (v) conclusion. Reports will be evaluated based on both clarity of exposition and sound engineering reasoning.
