In this lecture, we will talk about some of the other functional properties of materials that
are important for the designers today. Due to the emphasis on multifunctional materials,
more and more materials are chosen on the basis of a combination of mechanical and
non-mechanical properties. For example, new automobile body structure now demands
good thermal properties, surface hardness against denting, vibration damping and flame
retardance along with specific strength and stiffness. We have discussed already about
mechanical and surface properties of materials – let us discuss about a few other
properties now.
The properties that are very relevant at this stage are:
- Service Temperature
- Resistivity
- Dielectric Constant
- Magnetic Permeability
- Refractive Index
- Piezoelectric Constant
