It is one of the most common means of destructive testing. Simply bond two lap shears and pull. The reason shear strength is used to represent the strength of two bonded lap shears is that the load is parallel to the surface the load acts on. The shear stress causes one lap shear to displace with respect to the opposite lap shear.
