Theoretical crack path prediction
WebbThe model predicted the failure according to the accumulated damage rather than the analytical failure stress or strain. To evaluate the applicability of the proposed model, parallel simulation was carefully conducted corresponding to a series of two-stage loading tests, namely torsion-tension and compression-torsion tests, reported in the previous … Webb12 apr. 2024 · The first goal involves measuring the crack growth rate, path and other relevant properties as the crack grows under diverse loading conditions, including the stress ratio, eventually mixed mode, and environmental effects, such as corrosion, aging and thermal effects.
