Friction
'Dry' friction (as opposed to 'fluid' or 'lubricated' friction) is the force resisting lateral motion between two solid surfaces in contact.
It divides into:

double lap shear
Lap shear testing is used where an adhesive bond joins flat surfaces.
The required surfaces may be profiled, single, double or multiple, but standard test methods focus on a single joint.

single lap shear
Lap shear testing is used where an adhesive bond joins flat surfaces. The required surfaces may be profiled, single, double or multiple, but standard test methods focus on a single joint.

Insertion and withdrawal
Insertion and withdrawal testing involves applying and measuring the compressive force to an object to push it into a recepticle, then measuring the tension force to pull it out. This may be done for a single cycle or over multiple cycles.

cisaillement joint adhésif
Le test de cisaillement de joint adhésif est utilisé lorsqu'un adhésif joint des surfaces planes. Les surfaces utilisées peuvent être profilées, simples, doubles ou multiples, mais les méthodes de test normalisé se concentrent sur un seul joint.

Flexion
On utilise des tests de flexion car c'est un moyen de déterminer la réaction d'un élément lorsqu'il est soumis à des forces opposées sur une même étendue. Il permet d'évaluer à la fois la ductilité et la solidité d'un matériau.

Compressive shear
Compressive shear testing is simply the pushing apart of a material specimen by applying compressive force from opposite sides in a parallel plane. In this way, the material is stressed in a sliding motion.

Friction
Le frottement «sec» (par opposition au frottement «fluide» ou «lubrifié») est la force qui résiste au mouvement latéral entre deux surfaces solides en contact.
Il se divise en:

Closure torque
Closures and caps must be applied tight enough to maintain a seal and to resist working loose, but they must not be applied so tightly that the end user cannot reasonably remove them.
