“…That result is confirmed by other authors, such as Zhang et al [6]. As a consequence, the wear resistance of burnished materials is improved, which shows the comprehensive effects of burnishing as a finishing process (Hassan et al) [7], and a longer lifespan of industrial components can be expected, as explained by Hariharan and Prakash [8].…”

Ball-burnishing induces compressive residual stresses on treated materials by the effect of plastic deformation. The result is an increase in the fatigue life of the treated part, retarding the initiation of cracks on the surface. Compressive residual stresses have been previously measured by X-ray diffraction near the surface, revealing considerably high values at the maximum analyzed depth, in relation to other finishing processes such as shot peening. However, the maximum analyzed depth is very limited by using this technique. In this paper, the incremental hole drilling (IHD) technique is tested to measure residual stresses, being able to reach a 2-mm measuring depth. To that objective, a commercial strain gage is used and calibrated using finite element model simulations. A second Finite Element Model based on material removal rate is developed to obtain the equations to calculate the strain release through IHD. Finally, residual stresses are measured experimentally with that technique on two different materials, confirming that ball-burnishing increases the compressive residual stresses in layers up to 0.5¿mm deep for the testing conditions, which is a good response to industrial needs. The method proves to be suitable, simple and inexpensive way to measure the value of these tensions.Preprin

“…[3][4][5][6][7] Besides, as known, the V-groove can induce the stress concentration effect. [8][9][10][11] The cropping time and the cropping load, which directly affect the efficiency and the energy consumption, can be greatly reduced by the stress concentration effect. Some new different lowstress bar fine-cropping methods have been proposed based on the stress concentration in the last two decades.…”

In this article, a new controllable and near net low-stress bar fine-cropping system was proposed and developed by combined using the stress concentration effect of the prefabricated V-groove and the propagation crack. The bar finecropping experiments were successfully carried out using a new proposed cropping load control strategy. Although the level of the stress intensity factor range DK greatly influences the cropping time and the cross-section quality, the cropped-billets can be directly used for the precision forging industry without additional machining.

“…8,9 Applying uniform hydrostatic pressure during the uniaxial tensile process can improve the limit of forming properties to a certain extent. 10 The related research results showed that hydrostatic pressure has a minor effect on the constitutive relations of aluminum, aluminum alloy and copper bar. However, it has a significant effect on the fracture mechanism and ductility.…”

The sheet metal hydroforming technique is easy to achieve lightweight and is widely applied in the aerospace and automotive fields. In order to realize the reliability test for uniaxial tensile forming properties of sheet metals under the condition of three-dimensional stress, experimental apparatus and dedicated fixtures for uniaxial tensile tests of sheet metals under fluid pressure are designed in this article. The stainless steel 304 is employed for this experiment, and commercial finite element software ABAQUS is also adopted to study the deformation behavior of sheet metals under fluid pressure. The results indicate that when the fluid pressure of gauge length reaches a certain value, the specific region will present “double necking” and the peak values of equivalent stress and reduction rate are much lower than that of the conventional ones. When the strain rate is 0.01 s−1, the elongation of the 0.95-mm thickness sheet increases more obviously, reaching 24.1%. With fluid pressure, the fracture morphologies of stainless steel thin sheets and thick sheets are all ridge distributed from both sides to the center of symmetry, and tiny dimples distribute mainly in the rest parts. Based on the results of the experiment and finite element method, the uniaxial tensile forming properties of sheet metals under fluid pressure have been evaluated successfully and easily by this experimental apparatus.
