(chemistry) The strength with which a chemical bond holds two atoms together; conventionally measured in terms of the amount of energy, in kilocalories per mole, required to break the bond.
(engineering) The amount of adhesion between bonded surfaces measured in terms of the stress required to separate a layer of material from the base to which it is bonded.

1. The resistance to separation of mortar and concrete from reinforcing steel (or other materials) with which it is in contact. 2. All forces that resist separation, such as adhesion, friction due to shrinkage, and longitudinal shear in the concrete engaged by the bar deformations.
3. The applied unit load in tension, compression, flexure, peeling, impact, cleavage, or shear required to break an adhesive assembly, with failure occurring in or near the plane of the bond.

In chemistry, bond strength is measured between two atoms joined in a chemical bond.[1] It is the degree to which each atom linked to a central atom contributes to the valency of this central atom. Bond strength is intimately linked to bond order.
Bond strength can be quantified by:
- bond energy: requires lengthy calculations, even for the simplest bonds.
- bond dissociation energy
Another criterion of bond strength is the qualitative relation between bond energies and the overlap of atomic orbitals of the bonds (Pauling and Mulliken). The more these overlap, the more the bonding electrons are to be found between the nuclei and hence stronger will be the bond. This overlap can be calculated and is called the overlap integral.
