Numerical Reconstruction of Residual Stress Fields from Limited Measurements [PDF]
Advanced Materials Research, 2014 By finding stress states which are consistent both with any existing experimental measurements and with elasticity theory, residual stress fields can often be reconstructed from incomplete measurement data. We discuss such methods of residual stress reconstruction, their implementation using finite element analysis, and the measurement strategies which

A method for reconstruction of residual stress fields from measurements made in an incompatible region [PDF]
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 ...

Image-Based Stress Field Reconstruction in Complex Media [PDF]
, 2018 In many instances in life, materials are subject to deformation at high rates, for example: impact, crash, metal forming or pulsed welding. In this context, the transient and inhomogeneous nature of such loading as well as the strong multi-physic couplings induced by quasi-adiabatic conditions make: the experimental capture of the mechanical response ...

Voxel‐Based Full‐Field Eigenstrain Reconstruction of Residual Stresses [PDF]
Advanced Engineering Materials, 2023 Inverse eigenstrain (inherent strain) analysis methods are shown to be effective for the reconstruction of residual stresses in plane eigenstrain problems (continuously processed bodies) while conversely residual stress reconstruction in discontinuously processed bodies is extremely challenging and necessitates the use of complex regularizing ...

Reconstruction of a 2D stress field around the tip of a sharp material inclusion [PDF]
Procedia Structural Integrity, 2016 AbstractThe stress distribution in the vicinity of a sharp material inclusion (SMI) tip exhibits a singular stress behavior. The strength of the stress singularity depends on material properties and geometry. The SMI is a special case of a general singular stress concentrator (GSSC).

Holographic reconstruction of gravitational perturbations in AdS/CFT and implications for celestial conformal field theory [PDF]
Journal of High Energy PhysicsWe 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 ...
