Stress concentration

TL;DR: In this article, a short crack growth mechanism and kinetics were studied under symmetrical push-pull straining in austenitic stainless 316L steel and two different regimes in short and long cracks were identified.

TL;DR: In this article, notched specimens with a stress concentration factor common in many structural components have been subjected to severe shot peening process and the results indicate a very significant fatigue strength improvement for severely shot peened specimens in spite of their very high surface roughness.

TL;DR: In this article, the influence of pore aspect ratio on strength and Young's modulus of porous sandstones has been investigated in two-dimensional numerical simulations (RFPA 2D ).

TL;DR: In this article, an enriched ply element is developed, such that a matrix crack can be modelled explicitly within its domain, and an enriched cohesive element was developed to incorporate the boundaries of matrix cracks on the interface.

TL;DR: In this paper, the authors take a more fundamental approach based on continuum micromechanics, where the loading applied at the concrete level, is first concentrated (downscaled) to maximum stresses related to cement paste volumes which are directly adjacent to the aggregates, i.e. to the interfacial transition zones (ITZ).
