Shakedown modeling of unsaturated expansive soils subjected to wetting and drying cycles
E3S Web of Conferences, 2016 It is important to model the behavior of unsaturated expansive soils subjected to wetting and drying cycles because they alter significantly their hydro-mechanical behavior and therefore cause a huge differential settlement on shallow foundations of the ...

Shakedown analysis of red mudstone fill material with different water contents
Journal of Rock Mechanics and Geotechnical EngineeringUnderstanding the shakedown behavior of fill material is paramount to estimate the deformation stability of railway subgrade. Especially for red mudstone fill material (RMF), the noticeable overestimation of bearing capacity would be encountered if the ...

Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 9, Page 3738-3750, September 2026.ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...

Tracking Active Site Formation during Oxidative Activation of Copper-Exchanged Zeolites for Methane-to-Methanol Conversion. [PDF]
Adv Sci (Weinh)The oxidative generation of Cu(II) active sites in Cu‐exchanged zeolites for the CH4‐to‐CH3OH conversion has been studied. Complementary in situ/operando spectroscopic techniques highlight that the formation rate and the stability of different Cu(II) species are governed by their structure and the zeolite topology.

Deformation behavior of K0-consolidated soft clay under traffic load-induced stress paths
Yantu gongcheng xuebao, 2017 Under traffic loads, the magnitudes and directions of the principal stresses applied in the soil elements of soft subgrade change simultaneously. Namely, as the shear stress changes in amplitudes, the principal stress axes continuously rotate.
