    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
