摘要：

Methods of integral monitoring of the accuracy of calculated determination of viscoclastic characteristics were developed and make it possible to indicate the confidence intervals of the values of the determined parameters. The selection of a mathematical model for which the relative error of difference of the calculated values of the parameters from the average values is smallest will allow increasing the accuracy of prediction. The use of methods of refining the calculated parameters based on experimental stress-strain diagrams and iterative recalculation of these parameters brings the calculated values of the parameters closer to the experimental values, narrowing the confidence intervals and thus increasing the accuracy, of the prediction.
