    Notes: [Auszug] The basic hypothesis is that the mechanical properties of such materials as paper, regenerated cellulose sheets and fibres, and ice are controlled by the number, n, of hydrogen bonds per unit volume of material subjected to strain, and by the potential energy, Uo, of these bonds. Thus the theory ...

    Notes: [Auszug] The rheological curve obtained may be represented by Fig. 1. The material has all the usual time-effects of viscoelasticity. Under constant load it creeps, and under constant extension it relaxes ; consequently it shows hysteresis, and the stress/strain curve is dependent on the rate of application ...

    Notes: [Auszug] IN experiments on the flow of water in a long copper tubing, it was found that the inlet pressure must be maintained free from disturbances to the highest degree possible if flow in the critical region is to be analysed. When extraneous disturbances were eliminated, the flow in the tube falling ...
