Sample for uniaxial creep tests in a state of tension, especially to conduct tests on thin sheets and foils

摘要

the sample is in the form of plates (3) of the outline rectangle, situated between the outer rings (1) and the internal plates (2, 2 ') of the outline rectangles and is composite with both rings (1) as well as internal plates (2, 2') spoinami (4) or zgrzeinami. the inner plate (2 ') has a circular hole with a radius (r1) located so don't take my word with the outer ring (1).in an alternative solution, the inner plate has a radius of the radius equal to internal external ring (1).
