Since the 1960s, the use of plastics, synthetic rubbers, and other polymeric materials has been widespread. Because of their formability, polymers have impacted engineering and materials science. While they are low-cost manufacturing materials, their service lives are also lower with a short, distinct lifespan.

Advanced polymeric materials experience failure caused by several factors, including defects, loss of plasticizer, poor thermal stability, flammability, and environmental degradation. For instance, embrittlement and cracking as the result of UV or chemical exposure will affect a polymer’s inherent high degree of elasticity.

Residual stress, as a result of processing, can also initiate environmental stress-cracking and pressure as a result of snap-fit assemblies can result in impact fractures at the time of manufacture.
