Originální abstrakt

Stability loss during displacement-controlled loading is possible due to the low rigidity of the loading machine. This stability loss appears as a jump in measured parameters (catastrophe), while needed dependency is not obtained. Here, a procedure is used for recognition of this problem and its correction in the case of fracture tests on specimens of lime plasters containing meta-kaolin MEFISTO K05. Values of fracture energy from the measured load-deflection diagram without corecction were overestimated by about 6%.
