... in the absence of a solvent environment, no shattering will occur. The converse of this event is also true; that is, shattering does not occur in the absence of stress with solvent exposure. However, when PC material is stressed in the presence of a solvent environment, solvent-induced or environmentally induced...

..., materials around the crack tip can undergo three types of deformation modes: by plastic yielding, by creep, and by environmental attack. A deformation zone is associated with each type of deformation—the plastic zone, the creep zone, and the environment-affected zone (EAZ)—all of which are time dependent...

Similarly, a specimen may be tested with a standard liquid on its surface to determine the craze resistance of a material to a given environmental factor for a given time. This method was used ( Ref 44 ) to determine...

Brittle fractures, rather than ductile fractures, are more often the subject of a failure investigation, because they are often sudden, unexpected, and sometimes catastrophic. Similar to metals, many nonmetallic materials...
