Material properties: properties matter
Learning Outcomes
- Contrast plastic deformation with elastic deformation
- Generalize the relative positions on a logarithmic plot of strength versus density and Young’s modulus versus density of several metals, ceramics, and polymers
- Compare and contrast long-range and short range order
- Recall several examples of ordered solids in each of the three material classes (metals, ceramics, and polymers)
- Using the face centred cubic crystal structure, illustrate how the theoretical density of a polycrystalline metal can be calculated from knowledge of the crystal structure, atomic radius, and atomic weight
- Using the rock-salt crystal structure, illustrate how the theoretical density of a crystalline ceramic can be calculated from knowledge of the crystal structure, atomic radius, and atomic weight
- Summarize the packing of atoms in organized solids in terms of their one dimensional, two dimensional, and three dimensional packing fractions
