Behavioral properties of adhesives exposed to variable stresses and their ability to withstand strain without breaking, are vital when determining the most suitable adhesive for an application.

The Poisson’s ratio is commonly used in the designing of new structures because it allows engineers to consider the expected dimensional changes of a given material when under load.

The fracture toughness determines the overall resistance of a material against a load that is applied resulting in crack extension and also crack growth of a specimen that contains a fatigue pre-crack.

Understanding the relative expansion/contraction characteristics of two materials in contact is critical to determine application success.

Glass transition temperature ensures the right application is established given that some adhesives will operate in their glassy state, while others will perform when they are soft and supple.

Understanding the amount of shear force that can be exerted on a lap joint before failure occurs is an important measurement for product qualification.

Understanding how much force is required to progressively separate two bonded, flexible adherends, provides product engineers with vital information to understand the actual strength of an adhesive.

Product engineers consider this a highly valuable investigation as it enables greater application of adhesives in non-uniformed situations, helping to maintain appropriate adhesive coverage.

Volumetric shrinkage testing is an important diagnostic that enables to understand part deformity and any associated changes in part stiffness and shape that can lead to long term failure of a finished product.

Establishing the level of direct impact and penetration an adhesive is able to withstand, provides a common reference point when comparing different candidates.
