First row rotating blades of four axial-flow compressors were prematurely fractured. Previous investigations showed that the site atmosphere contains corrosive compounds which lead to an increase in possibility of pitting on the blades. It was also revealed that the crack was originated from two corrosion pits. Thus, this work is conducted to ascertain which of fatigue or stress corrosion crack...

Fatigue fracture simulation based on phase field methods is a promising numerical approach. As typical continuum approach, can naturally simulate complex fatigue behavior. Moreover, the cracking natural result of without additional criterion. This study first introduced principle, then reviewed some recent advances in for modeling, and gave representative examples macroscale, microscale, multis...

Traditionally, fatigue cracking in asphalt pavement means failure, which is the basis for controlling design thickness of pavements. In fact, failure pavements includes three stages: cracking, crack expansion, and structural failure. Therefore, this paper aims to investigate life bottom-up concrete (AC) considering different stages The dynamic modulus AC grades was experimentally determined. te...

Variant Stochastic cracking is a significantly more resilient approach to adaptive indexing. It showed [1]that Stochastic cracking uses each query as a hint on how to reorganize data, but not blindly so; it gains resilience and avoids performance bottlenecks by deliberately applying certain arbitrary choices in its decision making. Therefore bring, adaptive indexing forward to a mature formulat...
