Shear testing is different from tensile and compression testing in that the forces applied are parallel to the upper and lower faces of the object undertest. Materials behave differently in shear than in tension or compression, including different values for strength and stiffness. Lap shear testing is performed to determine the shear strength of an adhesive that is applied to two metal plates and pulled to failure. It can be used to compare between adhesive types or different lots within the same adhesive.
Shown below are a few of the standards that employ shear strength testing:
Apparent Shear Strength of Single-Lap-Joint Adhesively Bonded Metal Specimens by Tension Loading (Metal-to-Metal) is the most common standard DDL tests to involving shear.
