A method for reconstruction of residual stress fields from measurements made in an incompatible region

open access: yesInternational Journal of Solids and Structures, 2014
AbstractA method is introduced by which the complete state of residual stress in an elastic body may be inferred from a limited set of experimental measurements. Two techniques for carrying out this reconstruction using finite element analysis are compared and it is shown that for exact reconstruction of the stress field via this method, the stress ...

Reactivation of minor faults in a blind active fault area: A case study of the aftershock area of the 2000 Western Tottori Earthquake, Japan

open access: yesJournal of Asian Earth Sciences: X, 2021
The 2000 Western Tottori Earthquake (Mw 6.6, Mjma 7.3) in Japan occurred in an area where no active faults are known to exist. We examined the distribution, occurrence, paleostress field, and K–Ar ages of minor faults in the aftershock region of this ...

Research and Implementation of Three-Dimensional Spatial Information Characterization and Visualization of Fractures in Deteriorated Sandstone

open access: yesBuildings, 2023
Primary fractures significantly impacted the stability of surrounding rock in underground projects. Therefore, it is vital to find a solution for the problem of performing a non-destructive detection of rocks and extracting the internal three-dimensional

Isochromatic-Art: A Computational Dataset for Digital Photoelasticity Studies

open access: yesData, 2022
The importance of evaluating the stress field of loaded structures lies in the need for identifying the forces which make them fail, redesigning their geometry to increase the mechanical resistance, or characterizing unstressed regions to remove material.

A non-linear observer for unsteady three-dimensional flows [PDF]

open access: yes, 2007
A method is proposed to estimate the velocity field of an unsteady flow using a limited number of flow measurements. The method is based on a non-linear low-dimensional model of the flow and on expanding the velocity field in terms of empirical basis ...

Inside Out: Meet The Operators Inside The Horizon [PDF]

open access: yes, 2017
Based on the work of Heemskerk, Marolf, Polchinski and Sully (HMPS), we study the reconstruction of operators behind causal horizons in time dependent geometries obtained by acting with shockwaves on pure states or thermal states.

f(R,T) gravity [PDF]

open access: yes, 2011
We consider f(R,T) modified theories of gravity, where the gravitational Lagrangian is given by an arbitrary function of the Ricci scalar R and of the trace of the stress-energy tensor T.
