Abstract
Polymers are everywhere, also inside of the human body. Why polymers are so important? The most general answer is: because they are solid. With the term “polymer” we describe long chains consisted with repetitive structure, and longer chains tend to be solid. Classical forensic polymer engineering concerns a study of failure in solid polymer products. This area of science comprises fracture of plastic products, or any other reason why such a product fails in service, or fails to meet its specification. Environmental stress cracking (ESC) is one of the most common causes of unexpected brittle failure of thermoplastic (especially amorphous) polymers. The rate of ESC is dependent on many factors, including, for example, the polymer’s chemical composition, bonding, crystallinity, surface roughness, molar mass and residual stress. It also depends on the chemical nature of liquid media and the temperature of the system.
