bond strength

[′bänd ‚streŋkth]
(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.

bond strength

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.

It should be noted that the bond strength depends significantly on the connector design.
The present in vitro study was conducted at the Department of Prosthodontics and Crown and Bridge, SVS Institute of Dental Sciences, Mahbubnagar and Indian Institute of Chemical Technology, Hyderabad, to evaluate the tensile bond strength of heat-polymerized acrylic soft liners with various surface pre-treatment of denture bases.
The aim of the present study was to compare the shear bond strength (SBS) of metal orthodontic brackets bonded to long-term water-aged and fresh porcelain and composite surfaces.
Group C had the maximum mean shear bond strength of 12.231+-2.1Mpa, followed by Group A with 10.948+/-2.1Mpa and Group B with 7.621+-1.8Mpa.
To the best of our knowledge, no study has investigated the bond strength of BioRoot RCS using the push-out test.
Shear bond strength. Shear bond strength showed normal parametric distribution.
Results: The push-out bond strength of the CH group was significantly higher than that of the TAP, DAP and mTAP groups (p< 0.005).
However, the bond strength ([S.sub.L]) was calculated using the formula: [S.sub.L]=[pi] (R+r) [square root of (term)] [h.sup.2]+[(R-r).sup.2] (19).
In the lower part of the concrete (Table 1), the normal bond strength between the particles is consistent with the tangent bond strength.
The mechanism of the bond-slip and the distribution law of the interfacial bond strength of the CFSSTs under an ultimate bond load are studied.
This preliminary study recollected the test data on bond strength and corresponding slip value and maximum crack width from published literatures.
