.... The average behavior of the tested corneas under loading and unloading is visualized in Fig. 7 . Clearly, expected as a common feature among viscoelastic tissues, the average loading and unloading curves do not match due to hysteresis. The percentage hysteresis, calculated as the ratio between the area...

We constructed different viscoelastic tube set-ups: two straight tubes; one tube connected to two tubes of different elasticity...
