Uittreksel

Mol.-dynamics simulation is used to explore the influence of thermal and mech. history of typical glassy polymers on their deformation. Polymer stress-strain and energy-strain developments have been followed for different deformation velocities, also in closed extension-recompression loops. The latter simulate for the first time the exptl. obsd. mech. rejuvenation and overaging of polymers, and energy partitioning reveals essential differences between mech. and thermal rejuvenation. All results can be qual. interpreted by considering the ratios of the relevant time scales: for cooling down, for deformation, and for segmental relaxation. [on SciFinder (R)]
