Acoustoelasticity: Ultrasonic stress field reconstruction

Experimental Mechanics, 1996
Based on the theory of acoustoelasticity, a new ultrasonic stress reconstruction method—the generalized acoustic ratio (GAR) technique—is developed for locally plane structures and orthotropic materials. For given transit times of the three wave modes and the shear wave polarization angle, the local plane stress tensor is uniquely determined.

Stress field reconstruction in an active mudslide

Geomorphology, 2017
Abstract Meso-scale structures from gravitational slope deformation observed in landslides and deep-seated gravitational slope failures are very similar to those of endogenous ones. Therefore we applied palaeostress analysis of fault-slip data for reconstructing the stress field of an active mudslide in Pechgraben, Austria.

An Energy-Based Residual Stress Field Reconstruction Approach Using Limited Measurements

Volume 2B: Advanced Manufacturing, 2015
To characterize the residual stress distribution is very crucial for workpiece fatigue lifetime and structural integrity assessment. An energy-based residual stress field reconstruction approach using limited measurements is proposed. Firstly, the Ferguson spline interpolation technique is employed as the stress interpolation base of the 2-order stress

Identification of Stress Fields in a Customized Mandibular Reconstruction Based on a Photoelastic Model

Journal of Craniofacial Surgery, 2019
AbstractTumors, trauma and infections are the main reasons for subjecting a patient to a bone reconstruction made with the use of bone grafts or prosthetic elements, using for example components such as osteosynthesis plates, meshes and screws for their stabilization.This study focuses on the photoelastic analysis of a customized prosthesis of the jaw ...

An Inverse Method for Reconstruction of the Residual Stress Field in Welded Plates

Journal of Pressure Vessel Technology, 2010
Welding process is widely used in manufacturing of many important engineering components. For such structures, the most important problem is the development of residual stresses and distortion due to welding. Welding tensile residual stresses have a detrimental effect and play an important role in an industrial environment.
