Crazing - Wikipedia

Crazing is the phenomenon that produces a network of fine cracks on the surface of a material, for example in a glaze layer. Crazing frequently precedes fracture in some glassy thermoplastic polymers.As it only takes place under tensile stress, the plane of the crazing corresponds to the stress direction.
