“…The yield onset [15,16] also can be used for residual stress characterization. Furthermore, Wang et al [17,18] developed iterative equations using dimensional analysis based on representative strain to determine the residual stress and elastic-plastic properties of materials. However, the method's abundance of fitting parameters makes it sensitive to experimental errors, which can lead to challenges such as solution uniqueness and difficulties in practical application.…”

Shot peening is a mechanical surface treatment that can introduce compressive residual stress and work hardening simultaneously. This work hardening, considered as a modification of the elastic region with plastic strain, can be modelled with two types of contributions: isotropic hardening and kinematic hardening. In order to characterize the mechanical properties of the treated surface using the instrumented indentation technique, the effect of the backstress associated with kinematic hardening should be studied, especially for works related to fatigue loading. In this paper, the distribution of three backstress components is obtained by shot peening simulations on a nickel-based alloy, Inconel 718, commonly used in the aerospace industry, and a series of indentation simulations are carried out using a spherical tip with different equivalent backstress levels. For Inconel 718, the third backstress component, which has the slowest evolution rate, is found to have the most significant influence on the response. However, compared to the effect of residual stress and cumulated plastic strain, the effect of backstress can be neglected.

“…Except these, the methods that are based on indentation tests use various types of indenters and indentation tests for the prediction of residual stresses [5,6]. These methods require knowledge of some mechanical properties and inverse calculation for residual stress prediction [7,8]. Furthermore, part size and shape restrict the application of some methods such as ring core, deep hole drilling and sectioning methods.…”

Residual stresses in cold extruded parts play an important role in both component lifetime and succeeding in manufacturing performance. When a cold extruded part is used directly, the lifetime of the part depends on the residual stresses induced during cold extrusion. On the other hand, if the part is exposed to post operations such as machining, residual stresses may cause distortions. Despite their importance, there are only a few residual stress measurement methods to assess axial residual stresses in full cylindrical thick components of massive forming. As high-energy X-ray and neutron diffraction methods are less available and considerably expensive, the contour method may be an alternative providing the accurate assessment of residual stresses without requiring specialized facilities. In the present work, residual stresses in cold extruded rods are determined via the contour method for various extrusion ratios. The finite element analyses for the same conditions are also carried out to provide the comparison to the contour method. The results indicate that the contour method can be a valuable candidate for the measurement of axial residual stresses in cold extruded thick components.

“…Due to the large number of coefficients in the equation, the solution is more complicated. Based on the analysis of the finite element simulation results, Wang [11,12] proposed a fitting equation for the indentation response parameters and material properties. The relationship between residual stress, material properties and indentation parameters were established by dimensional analysis.…”

In this paper, a novel method was proposed to measure the residual stress and plasticity parameters of metal materials with yield plateau through continuous spherical indentation test. The indentation energy was selected as the indentation parameter to establish a dimensionless equation between the residual stress and material parameters through dimensional analysis method. The effects of residual stress and plastic parameters on the indentation response tests are studied, and the dimensionless function expressions are determined respectively when the specimen with or without residual stress based on the finite element analysis data of different residual stress levels. Based on the self-established inverse analysis, the yield strength (s y ), strain hardening exponent (n), ratio coefficient (a) and residual stress (s r ) can be obtained through indentation test. At last, the validation of the method presented in this paper was verified by simulating the material (SS400 and SM490) with the known material parameters.
