Abstrakt: The most likely causes for the rupture of ACV may be the rupture of the diaphragm in the region of the pole or breakage of the contact between the diaphragm and the body of the ACV at the attachment contour. The conditions for testing ACV in the region of the pole are rather accurately reproduced in cyclic inflation of a flat round sample. The accumulation of fatigue damage in ACV materials may be evaluated relative to decreased transparency and increase in residual deformations. Relative to fatigue resistance and elastic characteristics, polyurethane and reinforced organosilicone rubber may be used as ACV membrane materials. [ABSTRACT FROM AUTHOR]
