Base material
From apm
A gemstone like compound that has high performance in terms of some metric that is to be used as structural material in metamaterials.
Some of the the materials maximally possible performance is sacrificed in order to
- gain material amazing properties that otherwise would not be possible.
- avoid the necessity of many other material alltogether
Performance metrics may be things like:
- 0th derivative of energy ~~ toughness (in therms of the energy given by stress integrated over strain till irreversible damage)
- 1th derivative of energy ~~ ultimate tensile strength
- 2nd derivative of energy ~~ stiffness
- material density (in mass per volume)
- thermal conductivity (or its inverse)
- …
