Research of rotating and ultrasonic cycling fatigue in high-cycle regimes
Journal of Aeronautical MaterialsThe effects of stress ratio（R），loading condition，and MnS inclusion on the fatigue behavior of medium-carbon pearlitic high strength steel were investigated by the combination of rotating（frequency of 52.5 Hz，103-108）bending and ultrasonic （frequency of ...

A Non-Singular Analytical Technique for Reinforced Non-Circular Holes in Orthotropic Laminate
International Journal of Applied Mechanics and Engineering, 2020 The intricacy in Lekhnitskii’s available single power series solution for stress distribution around hole edge for both circular and noncircular holes represented by a hole shape parameter ε is decoupled by introducing a new technique.

Incompressible viscous flow near the leading edge of a flat plate admitting slip [PDF]
, 1975 The shear stress at the leading edge, calculated on basis of the Navier-Stokes equations and the no-slip boundary condition, approaches infinity. However, taking into account the mean free path of the molecules, which implies admitting a certain slip ...

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.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
