Their atomic structure
What property of metals allows them to absorb impact energy without immediate failure?
Ductility
Why do ceramics fail catastrophically under stress, unlike metals?
Ceramics have lower ductility than metals.
What is the primary reason for using copper over aluminium to transport electricity over larger distances?
Copper has higher thermal conductivity than aluminium.
What makes ceramics unsuitable for use in planes, bridges, or cars?
Brittleness

Ductility
Study Notes
- The text is about the introduction to materials, their internal structure, and the influence of properties on material selection and manufacturing.
- Materials have a specific internal structure that affects their properties.
- Metals are conductors of electricity, but aluminum is not as good as copper, but lighter and easier to transport for long distances.
- Ceramics are not typically used as structural materials due to their brittleness, which results in catastrophic failure.
- Metals and polymers are typically ductile, enabling absorption of impact energy without immediate failure.
- The atomic structure of materials, such as metals and ceramics, influences their chemical differences.
- Materials have various properties (strength, ductility, temperature stability, electrical and thermal conductivity) that differ based on atomic structure.
- The text mentions that the course goals are to understand materials' fundamental properties, identify relevant manufacturing considerations, and select appropriate materials for various applications.
- Ceramics are defined as a material class.
- Metals have excellent corrosion resistance for framing and roofing.
- The ability of materials to deform (ductility) is important for structural applications, as it allows for absorption of impact energy.
- Metals have lower strength than ceramics, but they do not fail catastrophically upon impact; instead, they dent.
- Polymers, like metals, are typically ductile.
- The text mentions the existence of a bonding classification of materials and bonding character of the five fundamental types of engineering materials.
- The six materials classes are mentioned, but not specifically listed.
