.... In other words, elastic strain causes small changes in the interatomic spacing and the stretching of interatomic bonds. The magnitude of modulus is a measure of the resistance to separation of adjacent atoms. Therefore, the modulus is found to be proportional to the slope of the interatomic force/distance...

... with lower densities than this are foams—materials made up of cells containing a large fraction of pore space. The moduli of most materials depend on two factors: bond stiffness, and the density of bonds per unit area. An interatomic bond is like a spring: it has a spring constant, S (units: N/m...
