ASE 324L: Aerospace Materials Lab, UT-Austin, ASE/EM, 2023 Fall, Instructor. Please check out our Canvas page and Piazza page.
The goal of this course is to study the deformation and fracture behavior of materials used in aerospace engineering. We will also learn structure-property relations, methods of characterizing material behavior, and use of properties in the design process. Topics include:
- Deformation behavior of hot and cold rolled steel
- Microstructure and dislocations
- Deformation behavior of a heat-treated aluminum alloy
- Solid solutions and crystalline structure
- High-temperature creep
- Deformation behavior of polymers
- Deformation behavior of fiber-reinforced composites
- Ceramics and Glasses
- Fractography and fracture toughness
- Environmental effects on fracture resistance
- Fatigue strength and Fatigue crack growth
- Materials Selection and case studies or other advanced topics
Besides lectures covering materials science and mechanics knowledge, we also provide ten corresponding lab sessions including:
- Tensile behavior of steel
- Microstructure/dislocation movies
- Tensile behavior of aluminum
- Microscopy and hardness tests
- Three-point flexure test of ceramics
- Relaxation of polyethylene
- Tensile behavior of fiber-reinforced polymers
- Fracture toughness testing
- Charpy impact testing
- Fatigue testing
