    Vicoelasticity - does anyone have the faintest idea what's going on?

    Eric Christison

      I have a bar 100mm long and 10X10 cross section, held at one end.

      I apply an axial load to the other end. The load and temperature remain constant over 100 seconds.

      I get the following displacement "curve" for a node at the end of the bar over the 100 seconds.

      Material is defined as follows:

      Obviously a deflection of -0.3mm at T=0 is nonsense but the bilinear nature of the curve is puzzling me as well.

      Any ideas?
