Stress field

TL;DR: In this paper, the authors used notch stress intensity factors (N-SIFs) to predict the fatigue behavior of mechanical components weakened by V-shaped re-entrant corners, where the singularity in the stress distribution makes any failure criterion based on elastic peak stress no longer applicable.

TL;DR: In this paper, the long axis of the tension gashes and stylolitic columns developed in limestones during a single phase of compressional deformation occur parallel to the direction of the maximum compressive stress (σ 1).

TL;DR: In this paper, a quality assurance system and a quality ranking scheme were developed for hydraulic fracturing stress measurements under specific conditions encountered in Chinese underground coal mines and a total of 97 stress data records of A and B quality were used to investigate the distribution characteristics of in-situ stresses within the coal districts.
