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. |
