Web1 de jul. de 2024 · This study proposes a calibrated weakest-link model for probabilistic life in low cycle fatigue (LCF) regime considering the geometric size effect and the … Web1 de dez. de 2007 · In the present paper a non-local stress approach for fatigue assessment based on weakest-link theory and statistics of extremes is presented. It is a non-local stress approach in the sense that it takes the complete stress field into account rather than just the highest local stress.
