Three‐dimensional crack monitoring by electrical resistivity measurement [PDF]
European Journal of Soil Science, 2004 Summary Soil cracks formed by natural processes play a key role in water and gas transfer. Patterns of soil cracks are, however, difficult to characterize. Our aim here is to assess the effectiveness of three‐dimensional electrical resistivity surveys in detecting soil crack networks.

Brittle Crack Roughness in Three-Dimensional Beam Lattices [PDF]
, 2005 The roughness exponent is reported in numerical simulations with a three-dimensional elastic beam lattice. Two different types of disorder have been used to generate the breaking thresholds, i.e., distributions with a tail towards either strong or weak ...

The Stress Intensity Factor of convex embedded polygonal cracks
Fracture and Structural Integrity, 2022 In the present work, a simple formula for the evaluation of the stress intensity factor (SIF) of convex embedded polygonal cracks has been proposed. This formula is structured as a correction factor of the Oore-Burns’ equation and is based on accurate ...

Fatigue of Fillet-welded Joint Assessment by the FEA Simulation of Damage Accumulation [PDF]
Инженерно-строительный журнал, 2011 Fatigue strength evaluation of non-continuous incomplete penetration fillet-welded joints transferring stress flow by the S-N criteria incorporating the «Hot-spot stress» or «Notch-stress» approaches is dubious since the characteristic stress at the ...
