In the other case the problem manifested as stress cracking
when the molded parts were exposed to a fluid used in a test designed to measure the internal stress in the part.
On the other hand, stress cracking
caused by a slow crack growth (SCG) mechanism is evaluated using a time-dependent tests while the fracture toughness is ignored.
Essential engineering parameters such as stress cracking
, oxidation resistance, UV degradation, and creep will be discussed.
Accel's uniform gradation and exclusive polymer formula, he adds, ensure a durable bond for strong and flexible joints; prevent stress cracking
, even in extreme hot and cold weather conditions; and, afford quicker, even filling of joints for interlocking concrete or brick pavements.--Fairmount Santrol, Sugar Land, Texas, www.fairmountminerals.com
It is my experience that environmental stress cracking
(ESC) is the leading mechanism of plastic component failure.
An impact guard sidewall design deflects debris for better sidewall protection while reducing stress cracking
, and the tire's rim guard protector shields the wheel for extended life and constant inflation.

. The tire's rim guard protector shields the wheel for extended life and constant inflation.
The results of a joint study on the environmental stress cracking
resistance (ESCR) of SABIC's thermoplastic materials used for medical device enclosures have been published, and will reportedly provide manufacturers with "new options" when it comes to materials choices.
Sidel says the new PET bottle offers improved resistance in terms of stress cracking
and creeping, as well as better stability throughout the supply chain.
New Apex SCR rigid PVC compounds make it possible for rigid PVC to replace polycarbonate (PC) in clear medical components such as connectors and check valves, obtaining comparable strength and excellent clarity while reducing or eliminating the stress cracking
that often occurs in PC at the interface with flexible PVC components such as tubing.
Coverage encompasses the specifics of various corrosion problems including stress cracking
and embrittlement, hydrogen attack, erosion corrosion, and liquid-metal embrittlement, as well as prevention measures; materials selection; chemical control of corrosive environments; requirements and conditions for corrosion control in the petroleum and petrochemical industries; corrosion evaluation; surface preparation and maintenance; fabrication techniques; and heat treatment, among other topics.
NCOC has identified stress cracking
due to sulphur-laden, highly corrosive gases as "the root cause of the pipeline issues" at Kashagan.
