Journal of Civil Engineering and Management, 1998 In some threaded joints, over a period of operation the conditions of compression are created, most likely owing to the prestress and bending caused by external loads. For elements in the cross-section in which the stresses are distributed unevenly, some

Mechanical Engineering Journal, 2021 In an experimental study that simulated a fast breeder reactor (FBR) vessel near the coolant surface, it was reported that the long distance travel of temperature distribution causes a new type of thermal ratcheting, even in the absence of primary stress.

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.

Influence of graphite morphology on static and cyclic strength of ferritic nodular cast iron
MATEC Web of Conferences, 2018 High silicon alloyed nodular cast iron consists of a purely ferritic matrix and graphite nodules, mainly. Varying wall thicknesses and manufacturing conditions result in different graphite morphologies throughout a structural component.

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 ...

Impact of Cyclic Loading on Shakedown in Cohesive Soils—Simple Hysteresis Loop Model
Applied Sciences, 2020 The objective of this study is to characterize the permanent deformations and to present a mathematical model that enables the prediction of permanent strain during cyclic loading. First, laboratory cyclic triaxial tests are conducted on sandy silty clay

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 ...
