Unique quantum stress fields [PDF]

open access: yesAIP Conference Proceedings, 2001
We have recently developed a geometric formulation of the stress field for an interacting quantum system within the local density approximation (LDA) of density functional theory (DFT). We obtain a stress field which is invariant with respect to choice of energy density.

Cylindrical shell with a circular hole under various loads: Comparison of analytical and numerical solutions [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2023
In this paper, the authors present the results of calculations of the stress field of a cylindrical shell weakened by a circular hole and under the influence of various loads: uniaxial tension, internal pressure and torsion.

Eigenstrain modelling of residual stress generated by arrays of Laser Shock Peeing shots and determination of the complete stress field using limited strain measurements [PDF]

open access: yes, 2012
This paper presents a hybrid explicit finite element (FE) /eigenstrain model for predicting the residual stress generated by arrays of adjacent/overlapping laser shock peening (LSP) shots where the use of a completely explicit FE analysis may be ...

Modification of the lithospheric stress field by lateral variations in plate-mantle coupling [PDF]

open access: yes, 2009
The presence of deeply penetrating continental roots may locally increase the magnitude of basal shear tractions by up to a factor of 4 compared to a layered viscosity structure.

Experimental investigation of fatigue crack initiation from notch for 2024 T351 Al-alloy

open access: yesFracture and Structural Integrity, 2020
In this investigation, fatigue criterion was established to predict crack-initiation at the tip of a notch in aged hardening aluminum alloy. This criterion was used to predict the residual lifetime in aeronautical structures using concept of local stress

ANALYSIS OF THE FAULT-BLOCK STRUCTURE AND STRESS STATE OF THE SEDIMENTARY COVER IN GAS-CONDENSATE DEPOSITS: BASICS OF THE TECTONOPHYSICAL APPROACH

open access: yesГеодинамика и тектонофизика, 2023
Consideration is being given to the tectonophysical approach to the reconstruction of structure formation mechanisms and stress-strain state of rocks in hydrocarbon deposits localized in the platform cover, which has a complex structure in terms of ...
