... in.) As stated earlier in this article, the uniaxial creep test may generate deformation data and/or rupture data. Historically, rupture data have been more prevalent than deformation data, because measuring the time to failure requires less sophisticated instrumentation than measuring deflection over time...

... to crazing. During a creep test, the specimen yields when it starts to deform plastically without a change in volume. Shear yielding usually precedes rupture and results in a permanent deformation in the stressed specimen; it is considered as a failure mode in polymers. Therefore, unlike the crazing process...

Hysteretic viscoelastic effects cause energy dissipation as heat, which can accumulate due to the low thermal conductivity of polymers, thus influencing failure mechanisms. The generalized uniaxial tensile creep behavior of plastics under...
