ASTM D5656 Stress-Strain Behavior of Adhesives in Shear by Tension Loading

ASTM D5656 Stress-Strain Behavior of Adhesives in Shear by Tension Loading

The ASTM D5656 test method covers the preparation and testing of thick-adherent lap-shear samples for the assessment of adhesives' stress-strain behavior in shear by tension loading. The purpose of this test method is to characterize the adhesive shear stress-strain properties that may be important in design considerations.

    Scope:

    The ASTM D5656 is a standard test method for determining the stress-strain behavior of adhesives in thick-adherent metal lap-shear joints. The data reduction and analysis of stress-strain curves acquired with thick-adherent lap-shear samples are covered by this test procedure. This test method can also be used to establish the proportional limit of the stress-stain relationship and to assess the stress-strain properties of an adhesive under shear. This information could be valuable in the design and study of adhesively bonded structures.

    Test procedure:

    The ASTM D5656 test technique involves applying a tensile force to thick-adherent lap-shear samples while simultaneously placing the adhesive in shear. The adherends employed in this standard test method are thick and robust, minimizing peel forces while obtaining the adhesive’s shear stress-strain properties. A finite element study of the thick adherent metal lap-shear specimen is presented in the referenced data, which calculates the effect of altering the adherent and adhesive stiffness. Because the stress is not completely uniform across the specimen’s over-lap, factors like adhesive stiffness, adherent stiffness, and the location of shear strain measurement along the bond’s length can impact the experimentally measured load-displacement curve.

    Specimen size:

    The ASTM D5656 test process uses a thick adherend lap shear test specimen.

    Data:

    An average value for shear stress, corrected strain, and modulus for each group of specimens tested is calculated and reported according to the ASTM D5656.
