RELAXATION OF CHIPBOARD BEAMS – ANALYSIS OF RESULTS OF EXPLORATORY RESEARCH
Journal Title: Civil and Environmental Engineering Reports - Year 2018, Vol 2, Issue 28
Abstract
The paper presents results of experimental tests and a theoretical analysis of the phenomenon of relaxation of chipboard beams. Three linearly viscoelastic rheological models were used for mathematical modeling of the rheology of the studied material. The constants of models were determined using experimental tests and the method of least squares. Through analyses of the obtained results it was found that the rheological behavior of the beam in the specified time is best described by a five-parameter model, consisting of standard and Kelvin-Voigt models connected in series. The final verification of the model can only be ensured by conducting long-term experimental studies using a multistage load program.<br/><br/>
