Original Abstract

Stabillity loss during displacement-controlled loading is possible due to the low rigidity of the loading machine (loading set-up). 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 selected cement-based composite. The reasons for overestimation of fracture energy evaluated from load-deflection diagrams without correction are indicated in the paper.
