An Inverse Method for Reconstruction of the Residual Stress Field in Welded Plates
Journal of Pressure Vessel Technology, 2010Welding 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.

Reconstruction of Stress Fields for the Aegean by a Finite Element Model
1980Since Ritsema 1974, a large number of focal plane data exist for the Aegean. In the present study, the reconstruction of the stress field due to the direction of maximum compression as found in Ritsema is attempted by a Finite-Element model. The fracture patterns thus simulated are compared with the results of photolineations determined from aerial ...

The problem considered in this paper is aimed at modification of earlier developed algorithms for the stress field reconstructions from discrete data on stress orientations in the earth’s crust. The modification is made for an elastic layer and takes into account the weight of the rockmasses and the vertical loads acting on the interfaces of the layer.

Computorized Reconstruction of Ultrasonic Velocity Fields for Mapping of Residual Stress
1977It is well known that the velocity of sound propagation through a solid is altered when a stress is applied. The velocity change is small, and dependent upon the type of wave being propagated as wall as the magnitude of the stress. Sensitivity is greatest to shear wave sound with the polarization vector parallel to the direction of stress. In this case,

An Energy-Based Residual Stress Field Reconstruction Approach Using Limited Measurements
Volume 2B: Advanced Manufacturing, 2015To 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

Abstract Residual stress (RS) significantly impacts the mechanical performance of components. Measurement of RS often provides incomplete data in terms of components of stress and spatial density. Employing such fields in finite element simulations results in significant modification of the field to achieve equilibrium and compatibility ...

This study reconstructs a two-dimensional stress field from measured strain data. The advantage of using stress functions is that the stress equilibrium and strain compatibility are automatically satisfied. We use the complex stress functions given by the finite series of polynomials.
