Tensile shear test

The tensile shear test is a basic procedure in surface technology that is used to evaluate the shear strength between different layers or materials. This test makes it possible to assess the quality and reliability of coatings, adhesives or other surface-treating materials.

During the test, a sample bearing the coating or material to be tested is clamped in a tensile shear fixture. By applying a tensile force to the sample and simultaneously applying a shear force along the interface between the materials, a shear stress is generated. This load leads to deformation and ultimately to failure of the sample along the interface or within the coating.

Tensile shear testing provides important information about the adhesive strength, cohesion and integrity of coatings or material bonds. It helps engineers and researchers to assess the performance of surface treatments, identify potential for unwanted delamination or failure and select suitable materials and processes for specific applications. By carefully performing and evaluating tensile shear testing, manufacturers can improve the quality of their products and ensure their reliability under real operating conditions.
