A common type of shear test which is frequently carried out on adhesives is known as lap shear testing. Adhesives are utilized in construction, electronic and aerospace applications. They can join parts together by transferring stress from one member (substrate) to another in a manner that distributes the stress more evenly than can be attained using mechanical fasteners.
