A model for stress relaxation is outlined in which the movement of dislocations over a volume dispersion of obstacles requires dislocation/dislocation interactions. The relation for the creep rate is modified for low temperatures which suggests that the behavior of stress relaxation rate is ‘‘athermal’’ and logarithmic in character.

    The compressive response of articular cartilage has been extensively investigated and most studies have focussed largely on the directly loaded matrix. However, especially in relation to the tissue microstructure, less is known about load distribution mechanisms operating outside the directly...

    - All earthquakes are followed by an aftershock sequence. A universal feature of aftershock sequences is that they decay in time according to the modified Omori’s law, a power-law decay. In this paper we consider the applicability of damage mechanics to earthquake aftershocks. The damage...

    Tests are described to measure the creep and relaxation response of aramid fibres with the specific aim of determining whether the visco-elastic response is linear or non-linear. Hitherto, creep and relaxation tests have been carried out in different circumstances and at different loads, which...
