Creep Behavior Modeling of a Marble Under Uniaxial Compression

摘要: Axial strain–time curves for a marble sample were obtained by performing uniaxial compression tests with step loading. strain rate–time data points then from the axial curves. One power function and one exponential selected literature to fit experimental creep data. Based on characteristics of plotted rate-time points, proposed as possible functions model By comparing goodness-of-fit aforementioned four through regression analysis, it was found that two better than functions. The showed very close levels has only parameters compared in which parameters. Therefore, is marble. This also related built-up combined spring-dashpot known generalized Kelvin model. parameter values are calculated relations exist between function.
