Pseudo-inverse method for the identification of non-homogeneous stress field in dynamic experiments
DYMAT 2009 - 9th International Conferences on the Mechanical and Physical Behaviour of Materials under Dynamic Loading, 2009The conventional recovery of the mean stress field in dynamic tests is not valid in case of non equilibrated-dynamic tests. Inverse techniques are well adapted to resolve this problem. Conversely, they need the resolution of a complex numerical problem.

Stress field and thrust kinematics: a model for the tectonic inversion of the cameros massif (Spain)
Journal of Structural Geology, 1992Abstract Alpine tectonics of the Cameros Thrust has been studied from several points of view: geometry (surface and sub-surface structure, three-dimensional outline of the thrust), kinematics (transport direction) and dynamics (characterization of the regional compressional stress field).

The Journal of Strain Analysis for Engineering Design, 2014
A modified stress function approach is developed for reconstruction of residual stress and eigenstrain fields from limited experimental measurements. The modified approach is successfully applied to three experimental case studies where residual stresses are introduced by surface peening.

Semi-Differential Reynolds-Stress Model and Field Inversion Symbolic Regression Optimization
AIAA JournalThe Reynolds-averaged Navier–Stokes (RANS) framework incorporates two approaches for obtaining turbulent stresses: the algebraic eddy-viscosity model and the full transport-equation model. The latter is generally considered to have more potential than the former when applied to complex flows but still displays limitations in predicting streamwise ...

Inverse Analysis of Pre-stressed Soft Tissues via the Virtual Fields Method
Quantifying the in vivo mechanical properties of soft tissues is essential for developing patient-specific models for precision medicine. The Virtual Fields Method (VFM) determines material parameters from full-field deformation measurements by minimizing the difference between internal and external virtual work, avoiding the iterative forward ...Manuel Lucas Sampaio de Oliveira +4 more
