Accelerated creep testing of polymers using the stepped isothermal method
Polymer Testing, 2013 The increasing use of polymers in engineering applications requires suitable accelerated test methods for predicting their long-term behavior. The stepped isothermal method (SIM), originally developed for product testing of geosynthetics, was successfully applied in the presented work to characterize the long-term creep behavior of polypropylene up to ...

Creep dynamics of viscoelastic interfaces [PDF]
, 2013 The movement of a purely elastic interface driven on a disordered energy potential is characterized by a depinning transition: when the pulling force S is larger than some critical value S_1 the system is in a flowing regime and moves at a finite ...

A new swelling - creep model for red-bed mudstone and its application
Frontiers in Earth ScienceIn the red-bed region, engineering structures often encounter safety risks due to the swelling and creep properties of mudstone. Presently, there is a deficiency in constitutive equations capable of characterizing mudstone behavior under combined stress ...

Physical Mechanisms for the Variable Spin-down of SGR 1900+14 [PDF]
, 1999 We consider the physical implications of the rapid spindown of Soft Gamma Repeater 1900+14, and of the apparent "braking glitch", \Delta P/P = l x 10^-4, that was concurrent with the Aug. 27th giant flare.
