Online stress monitoring during laser-directed energy deposition based on dynamic contour method

Virtual and Physical Prototyping
Deformation and cracking caused by internal stress have been a long-standing challenge in the field of metal additive manufacturing. This paper presents a novel method for real-time stress assessment of laser-directed energy deposition (LDED) based on ...

pyCM: An open-source computational framework for residual stress analysis employing the Contour Method

SoftwareX, 2020
The contour method for assessing residual stress is a widely accessible method in terms of the equipment required and experimental protocol. However, its application is hampered by the absence of a common computational framework to reconstruct the ...

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

International 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 ...

Shape derivative of an energy error functional for voids detection from sub-Cauchy data

Electronic Journal of Differential Equations, 2016
We study a new framework for a geometric inverse problem in linear elasticity. This problem concerns the recovery of cavities from the knowledge of partially overdetermined boundary data.

Reconstruction of orientation of stresses acting in infinity within the Kovdor ore body based on field determinations

Vestnik MGTU, 2017
Mining Institute KSC RAS has conducted research which aim is to study the possibilities of increasing the tilt angles of pit walls in massifs of solid rock. One of the problems the solution of which will contribute to achieving this goal is to determine the direction of the maximum component of principal stresses in intact massif on the "infinity ...

Holographic reconstruction of gravitational perturbations in AdS/CFT and implications for celestial conformal field theory

Journal of High Energy Physics
We begin by reexamining the holographic reconstruction of scalar fields in four- dimensional anti-de Sitter spacetime, adopting a purely Lorentzian signature derivation, reproducing earlier results of HKLL and generalizing to arbitrary boundary metrics ...
