ABSTRACT Fatigue failure in aerospace structures is critically influenced by stress concentrators such as notches, which reduce service life and compromise safety. This study experimentally investigates the fatigue behavior of Al7075‐T6 alloy under rotating bending (R = −1, 60 Hz), considering notched and unnotched conditions.

Fracture behavior of grain boundaries in (U,Pu)O2 fuels: An atomistic study
Abstract Classical atomistic simulations using the Cooper–Rushston–Grimes potential were carried out to observe the stability and the fracture properties of six special grain boundaries in (U1−x${\rm U}_{1-x}$, Pux)O2${\rm Pu}_x){\rm O}_2$. The formation energy decreases as a function of Pu content, while the cleavage energy increases.

Experimental Study on Liquefaction Characteristics of Saturated Sand–Silt Mixtures
Soft soil layers, such as sand and silt, are prone to seismic liquefaction when exposed to ground shaking induced by earthquakes. Many severe earthquake disasters in history can be attributed to weak ground conditions. While the dynamic behavior of sandy soils and silts has been widely investigated, real‐world liquefiable sites often consist of soils ...
