Fig. 8: Measuring the changing of pressure and pressure area
under shear-load using pressure sensitive films [1]
(Tyton connection with a diameter of 150 mm).
A Without load: Relevant surface pressure of 6.6 bar.
B 1. Step: shear-load of 971 N: Relevant surface pressure of 5.5 bar.
C 2. Step: shear-load of 1942 N. Relevant surface pressure of 3.1 bar.
D 3. Step: Shear-load of 2914 N. Relevant surface pressure of 3.1 bar.
E 4. Step: Shear-load of 4500 N. Relevant surface pressure of 2.6 bar.
F After 1,5 hours, under a shear-load of 4500 N: No significant change
in comparison to E.
