Interatomic bond stiffness
Nettet1. okt. 2016 · The resulting structure will have tension and shear stiffness, but will not have a torsion stiffness. To eliminate this shortcoming, we introduce the second set of N truss members of hyperboloid, twisted in the opposite direction (): (3) c n ′ = def − R s n + a i + R s ˜ n ′, s ˜ n ′ = def P (− γ i) · s n. If γ = π / N, then the set of trusses of the first and … Nettetbonding energy between the two atoms. • To break the bond, this energy must be supplied from outside. • Breaking the bond means that the two atoms become infinitely …

NettetYoung's modulus Y for a material is defined as the ratio of tensile stress to tensile strain. The tensile stress is the force per unit area F/A, and the strain is the proportional increase in length parallel to the applied force δx/x. If we divide the area elements of A = y 2, we have one intermolecular bond and its force F to consider.
