The thickness profile of a crazing is like a sewing needle: the very tip of the crazing may be as thin as several atoms, as the distance from the tip increase, it tends to thicken gradually with the rate of the increase diminishing with distance.
Therefore, the growth of crazing has a critical distance from the tip. A craze is different from a crack in that it cannot be felt on the surface and it can continue to support a load.
Furthermore, the process of craze growth prior to cracking absorbs fracture energy and effectively increases the fracture toughness of a polymer.
The initial energy absorption per square meter in a craze region has been found to be up to several hundred times that of the uncrazed region, but quickly decreases and levels off.
Crazes form at highly stressed regions associated with scratches, flaws, stress concentrations and molecular inhomogeneities. Crazes generally propagate perpendicular to the applied tension.
Crazing occurs mostly in amorphous, brittle polymers like polystyrene PS , acrylic PMMA , and polycarbonate ; it is typified by a whitening of the crazed region.
The white colour is caused by light-scattering from the crazes. Besides, the production of crazing is a reversible process, after applied compressive stress or elevated temperature higher than glass transformation temperature , it may disappear and the materials will return to optically homogeneous state.
Shear banding is the narrow region with high level of shearing strain from local strain softening, it is also very common during the deformation of thermoplastic materials.
One of the main differences between crazing and shear banding , is that crazing occurs with an increase in volume, which shear banding does not.
This means that under compression, many of these brittle, amorphous polymers will shear band rather than craze, as there is a contraction of volume instead of an increase.
In addition, when crazing occurs, one will typically not observe "necking," or concentration of force upon one spot in a material.
Rather, crazing will occur homogeneously throughout the material. Rubber particles are often used to toughen thermoplastic materials, after modified, the ability of absorbing energy will be increased significantly.
For some brittle plastic materials, they can even go through brittle-ductile transformation. Previously, the rubber particles were considered as the main contributor to the increased energy absorption.
It was proposed that rubber particles might gather around crack tips under tension and impede the growth of crack, or the contraction of rubber particles induced the decline of glass transformation temperature of the matrix.
Schmitt and Bucknall developed the mechanism of rubber toughening according to the existence of stress whitening and shear yielding when the stress is lower than fracture strength.
To specify, yielding happens in the form of crazing or shear band, which can consume a large portion of deformation energy.
Crazing can take place in glassy polymers under environmental effects. It is troublesome because it requires a much lower stress state and sometimes it happens in a long delay, which means it's hard to detect and avoid.
For example, the PMMA containers in daily use is quite resistive to humidity and temperature without any visible defects.
But after they are machine-washed and then left in air for one or two days, they will shutter abruptly when wet with gin.
There are many theories that tried to explain the environmental effects upon formation of crazing, among which surface energy reduction and plasticization are widely accepted and well developed.
However, due to the complicity of the environmental effects, especially the effects in organic environment, it's hard to find a general solution and remove the effect completely.
Crazing is also seen on single ply roofing membranes, joint sealant, and on concrete when good concrete practices are not followed.
Crazing is a glaze defect of glazed pottery. Characterised as a spider web pattern of cracks penetrating the glaze, it is caused by tensile stresses greater than the glaze is able to withstand.
The Chinese in particular enjoyed the random effects of crackle and whereas in Ru ware it seems to have been a tolerated feature of most pieces, but not sought, in Guan ware a strong crackle was a desired effect.
Crazing is also used as a term in odontology to describe fine cracks in the enamel of teeth.
