Abstract

Figures of merit are values that denote the benefit of key material properties in terms of mechanical and thermal performance. Mechanical figures of merit relate to stiffness, strength, and mass. The stiffness of a material is proportional to its elastic modulus E, while the mass of a material is proportional to its density ρ.
