ASTM D3166 Fatigue Properties of Adhesives in Shear by Tension Loading

ASTM D3166 Fatigue Properties of Adhesives in Shear by Tension Loading

The ASTM D3166 test method specifies the preparation, loading, and testing parameters for measuring fatigue strength in shear by tension loading of adhesives on a standard specimen under specified conditions. The fatigue properties are a function of the specimen geometry.

    Scope:

    The ASTM D3166 is a standard method for evaluating the fatigue strength of adhesives in shear by tension loading, with the goal of defining structural adhesives on a specific metallic substrate, using standardized specimens under specified conditions. While this test method is designed for metal-to-metal applications, it can also be used to measure the fatigue properties of adhesives with plastic adherends if the thickness of the plastic adherends is taken into account.

    ASTM D3166 testing can be used to assess the fatigue performance of different adhesive systems or to compare them to the fatigue performance of joints created by other joining methods, utilizing simple joint geometries such as lap-shear or T-peel samples.

    Specimen size:

    For the ASTM D3166 test procedure, tension lap-shear specimens with precise dimensions and grip ends suitable for usage in the particular testing equipment are used.

    Data:

    In accordance with the ASTM D3166, the location of failure (adhesive or joint material) and nature of failure if in the adhesive are reported for each specimen.

    Conclusion:

    The ASTM D3166 is a standard method for evaluating the fatigue strength of adhesives in shear by tension loading, with the goal of defining structural adhesives on a specific metallic substrate, using standardized specimens under specified conditions.
