For ABS, it is well known that the deformation mechanisms include crazing
(33), (34), shear yielding (35), cavitation of rubber particles, and the induced yielding in matrix (36).
While all fracture surfaces from the tests reported in Table 3 showed evidence of crazing
and crack initiation, it should be noted that the final separation of the pipe wall occurred by yielding, drawing, and rupture .
The deformation behavior was found to consist of both shearing and crazing
in which the shear mechanisms prevailed on the surface while crazing
was active in the interior.
w] and SCB content as PE100, it did not exhibit a transition from crazing
to shear deformation as did PE100.
has been categorized as a viscoelastic deformation process like creep and stress relaxation involving multiple localized deformation sites instead of bulk deformation.
One of the goals of this paper is to correlate the residual mechanical properties measured in the previous study to crazing
stress, relative craze density, and strain rate.
It may be suggested that polymers can be toughened by adding some fillers to promote crazing
Some limitations to this method are the ineffectiveness in measuring low amounts of crazing
and the necessity of the instrument to be in close contact with the surface being measured.
A PVC/MBS molded product also seems to satisfy plane strain requirements near the notch in the Izod impact test on a test piece having a general thickness, and it is estimated that crazing
deformation first occurs in a notched portion, followed by shear yield deformation and finally crack destruction .
If the toughness is improved mainly through crazing
, the toughener phase must exhibit good interfacial adhesion with the matrix , and acts not only as a stress concentrator but also as a craze stabilizer [2, 18].
Despite multiple crazing
in PE1, the overall break separation remains lower than that for PE2 due to the lower value of [lambda] of the fibrils in any given craze of PE1.
impact resistance is improved by shear yield  or by crazing
rather than shear yield .
The enhanced ductility of rubber-toughened plastics and their resistance to fracture have been explained via a mechanism of crazing
and shear yielding of the glassy polymer matrix (1).
The failure of amorphous polymers in the glassy state is often preceded by a dilatational deformation process referred to as crazing
y], brittle fracture occurs with crazing
, and when [[Sigma].
