Numerical Simulation on Change of Equivalent Permeability of Coal Rock Under Different Stress Ratios
Meikuang Anquan, 2020 We describe the mechanics characteristic of the coal rock by adopting B-B failure criteria. Moreover, we study the crack evolution rule of coal rock, the internal flow distribution of coal rock and the equivalent permeability of coal rock under ...

Effect Of Single Overload Ratio And Stress Ratio On Fatigue Crack Growth
, 2013 In this investigation variation of cyclic loading effect on fatigue crack growth is the studied. This study is performed on 2024 T351 and 7050-T74 aluminum alloys, used in aeronautical structures. The propagation model used in this study is NASGRO model. In constant amplitude loading (CA), effect of stress ratio has been investigated.

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...
