Device for creep testing a sample

摘要

The invention makes it possible to carry out creep tests on samples of ceramic or any fragile material. The sample (1) bears on two lower supports (2) consisting of two parallel rollers (10) placed on a fixed base (9). The bending force is applied by means of a mobile device consisting mainly of a hemisphere (7) bearing on a concave surface (15) of a moving part (6) carrying the upper support points (4). The force is applied by using masses (16) positioned on a plate (12) integral with the hemisphere (7). Application to the effects of creep of various ceramics. <IMAGE>
