Interatomic bond stiffness

NettetHow can one relate the macroscopic spring-like properties of the particular metal to the stiffness of that metal's interatomic bonds (interatomic spring stiffness). Equipment a straight metal wire stretched on a frame, with a hanger for weights a millimeter scale for determining the position of the end of the wire NettetBond stiffness, S, is given by: where U = bond energy and r = atomic separation. When the stretching is small, S is constant and therefore the bond is linear-elastic. This …
