“…The drilling of a hole on this surface leads to a stress relaxation in the area around the hole. The new stress distribution in this region results in a deformation of the surrounding material, which is measured with installed strain gauges [21]. Several studies show the applicability of BHDM to determine residual stresses in thermally sprayed coatings [22][23][24][25].…”

Abstract:Residual stresses have been a major source of concern, as they are an inevitable consequence of manufacturing and fabrication processes. The magnitude of these stresses is often as high as, or at least, comparable to the yield strength of the material. In terms of arc sprayed coatings, the utilization of bore hole drilling methods presents some practical disadvantages as mechanical parameters (Poisson's ratio, Young's modulus) need to be identified in order to determine the residual stress distribution. Curvature techniques using Almen strips are cost-and time-effective methods that can be used for analytical quality assurance. Within the scope of this work, a quantitative study of the amount of residual stresses induced in a twin wire arc spraying (TWAS) process for a given combination of process parameters was conducted using the incremental bore hole drilling method, as well as the curvature method including Almen strips. Therefore, the effect of the primary gas pressure, substrate preheating temperature, and handling parameters, such as the spray angle and gun velocity, which influence the coating deposition as well as the heat input into the substrate, are examined. The experiments were carried out by using an iron-based cored wire with cast tungsten carbides as filling. The results of both methods are in an acceptable accordance with each other. Different stress fields were observed depending on the parameter settings.

“…The slice and contour methods are destructive, and the blind-hole and deep-hole methods are destructive too. The destructive methods belong to the category of stress release and would cause the damage of components, which is fatal and must be avoided [2], while nondestructive methods are more widely applied in recent years, such as X-ray diffraction technique [3,4], thermoelastic stress analysis (TSA), and ultrasonic method [5]. TSA is a noncontacting and sensitive experimental stress analysis technique [6,7], which provides full-field stress data over the surface of a cyclically loaded specimen or component [8].…”

Residual stress has significant influence on the performance of mechanical components, and the nondestructive estimation of residual stress is always a difficult problem. This study applies the relative nonlinear coefficient of critical refraction longitudinal (L CR ) wave to nondestructively characterize the stress state of materials; the feasibility of residual stress estimation using the nonlinear property of L CR wave is verified. The nonlinear ultrasonic measurements based on L CR wave are conducted on components with known stress state to calculate the relative nonlinear coefficient. Experimental results indicate that the relative nonlinear coefficient monotonically increases with prestress and the increment of relative nonlinear coefficient is about 80%, while the wave velocity only decreases about 0.2%. The sensitivity of the relative nonlinear coefficient for stress is much higher than wave velocity. Furthermore, the dependence between the relative nonlinear coefficient and deformation state of components is found. The stress detection resolution based on the nonlinear property of L CR wave is 10 MPa, which has higher resolution than wave velocity. These results demonstrate that the nonlinear property of L CR wave is more suitable for stress characterization than wave velocity, and this quantitative information could be used for residual stress estimation.

Residual Stress Analysis on Welded Joints by Means of Numerical Simulation and Experiments

Residual stress arising from welding processes is matter of great concern in industrial practice since it can affect geometry, mechanical behavior and corrosion resistance of components. In order to evaluate residual stress in welded joints and optimize postwelding heat treatments, a lot of work has been devoted to the improvement of measurement methods with increasing sensitivity and accuracy. The chapter presents and discusses some of the experimental techniques commonly used today to determine residual stress in welds and describes recent results and advancements. Destructive (sectioning, contour, hole-drilling, instrumented indentation) and nondestructive (Barkhausen noise, ultrasonic, X-ray and neutron diffraction) methods are illustrated to highlight the specific characteristics, advantages and drawbacks.
