摘要

The influence of the local state of stress on the predictability of the Beremin model is investigated. For this purpose, the Beremin model is used on a series of tensile experiments with varying constraints. One specimen series is used to calibrate the Beremin parameters. These are afterwards applied to all specimen series. For all series the test results are compared to the predicted 5% to 95% failure probability corridor calculated by the Beremin model. The results are then discussed in concern of the influence of the stress state on the predictability of the Beremin model.
