Study Notes
Materials' Selection
- Selection criteria include minimizing weight, volume, environmental impact, and cost, while enhancing performance
- Typical project requirements involve a compromise between conflicting objectives
- Each objective determines a judgment parameter, which helps in selecting materials
Where to Find Information
- Books and online resources (e.g., Material ConneXion) provide information on materials and their properties
- Architects and structural engineers typically specify products, not materials, and understanding material properties can assist in design decisions
Material Properties
- Materials are solid compounds used in production, with distinct chemical, physical, and mechanical properties
- A material is an aggregate of atoms or molecules bound together by chemical or physical bonds
- Material properties include reactions to external chemical and/or physical actions, which can be measured or calculated from other data
Chemical Bonding
- Chemical bonds derive from the sharing of electrons among two or more atoms
- Covalent bonds involve sharing electrons among atoms, while ionic bonds form between atoms with remarkable differences in electronegativity
Thermal Properties
- Thermal capacity is the property of a body to absorb heat, described by its specific heat
- Heat conductivity and thermal diffusivity are important thermal properties of materials
