26 Jul 2020 Bond strength represents the extent of bonding between two atoms forming a molecule. The larger the bond energy, the stronger is the bond

The Strength of Sigma and Pi Bonds. There is one important thing we should address when comparing the strength of a single bond with a double or a triple bond. Remember, that a multiple bond consists of one σ and one or two π bonds. Now, if we compare the single bond strength with the double bond, we have 88 kcal/mol :152 kcal/mol. bond (bŏnd) n. 1.

Bond strength is a measure of the ability of the units and mortar in masonry construction to remain bonded and resist applied stress and movement, particularly in tension. It is one of the most important properties of masonry, particularly in low-rise domestic and commercial buildings.

means bond strength equal to or more than propellant strength. eur-lex.europa.eu una unión mecánica fuerte significa una fuerza de unión igual o superior a la fuerza del propulsante. In bond strength adhesive-substrate test, when the fracture was cohesive within the adhesive, the values are very consistent with the mortar flexural strength; when the fracture was adhesive (at the interface adhesive-substrate), the flexural strength of the adhesive values are generally higher than flexural strength of the adhesives of the other analysed systems. That is, increase in bond strength leads to corresponding frequency increase and vice versa.
