Numerical Study of the Effect of Materials’ Plastic Behavior on Equibiaxial Residual Stress Measurement Using Indentation
Indentation is a new method for estimating residual stress. The plastic behavior of the materials under study can affect indentation parameters and, thus, influences the results of residual stress measurement. In this paper, the effect of yield stress and work-hardening exponent on the accuracy of residual stress measurements in steels and aluminums was studied. Results showed that, for m...
متن کاملOverview Residual stress Part 1 – Measurement techniques
Residual stress is that which remains in a body that is stationary and at equilibrium with its surroundings. It can be very detrimental to the performance of a material or the life of a component. Alternatively, beneficial residual stresses can be introduced deliberately. Residual stresses are more difficult to predict than the in-service stresses on which they superimpose. For this reason, it ...
متن کاملOil STUDY OF ULTRASONIC METHODS FOR NONDESTRUCTIVE MEASUREMENT OF RESIDUAL STRESS
The study of streas-induced birefringence has been continued in both polycrystalline and single crystal experiments. The effect is explained on the basis of nonlinear elasticity theory. Experiments indicate that dislocation activity does not strongly affect results in polycrystalline specimens, however, a pronounced influence may be observed in single crystals. Nonlinear elasticity theory has b...
متن کاملMeasurement of residual stress using laser-generated ultrasound
Most manufacturing processes result in residual stress. The level of residual stress can be high and could affect the structural integrity of the component. Without knowledge of the residual stress field, assessments are often overly conservative. There are many techniques available for residual stress measurement. Mechanical methods, such as centre-hole drilling, have been extensively used but...
متن کاملapplication of pulsed eddy current technique to stress and residual stress measurement
stress and residual stress are the main problems in the operating performance of materials. they are the principal causes of material failure and can affect life time of component. however measurement or predictions of them are typically difficult. two common non-destructive methods, x-ray diffraction and ultrasound are not reliable methods for subsurface residual stress measurements and destru...
