Element Analysis

Water-jet cavitation peening is a new technology for surface modification of metallic materials. Compress residual stress layer is induced by impact wave pressure in the submerged cavitating jets processing. Based on ANSYS/LS-DYNA finite element analysis software, residual stress field in the SAE1070 spring steel material surface induced by cavitate-jet water peening process is simulated, the magnitude and variation rules of the residual stress along the layer depth under different conditions is obtained. In order to verify the correctness of the numerical simulation, the size and distribution of residual stress by the X-ray diffraction method. The results show that the numerical simulation and experimental results are well consistent.

Main Effect

The interest on the application of the shot peening process to arrest and/or delay crack growth is rising. The main effect of the shot peening technique is to introduce a residual stress field that increases the working life of mechanical components. In this paper, it is presented the numerical simulation (FEM) of the shot peening process and the effect of introducing a residual stress field. Besides, the consequence of changing the sizes of the impacting ball is analyzed. This work also used the Crack Compliance Method (CCM) for the determination of residual stresses in beams subjected to a numerical simulation of a shot peening process. The numerical results obtained provide a quantitative demonstration of the effect of shot peening on the introduction of residual stresses by using different sizes of impacting balls and assess the efficiency of the CCM.

Compressive Residual Stresses

Shot peening is a manufacturing process intended to give components the final shape and to introduce a compressive residual state of stress inside the material in order to increase fatigue life. The modeling and simulation of the residual stress field resulting from the shot peening process are proposed. The behaviour of the peened target material is supposed to be elastic plastic with bilinear characteristics. The results demonstrated the surface layer affected by compressive residual stresses is very thin and the peak is located on the surface.

Inhalt: In diversen Branchen des Maschinenbaus wird Kugelstrahlen zur Steigerung der Bauteilfestigkeit eingesetzt. Die Auslegung der Verfestigung wird heute oft mit iterativen Versuchen vorgenommen. Im hier vorliegenden ersten Teil der Veröffentlichung, „Simulationsmodell und Eigenspannungsfeld“, wird eine wirtschaftliche Simulation auf Basis einer neuartigen Zellperiodizität vorgestellt. Diese erlaubt prozessrelevante Parameter vorherzusagen und resultierend auf die Eigenspannungsmessung zu verzichten. Ferner wird die in der Literatur nur selten behandelte Inhomogenität des Eigenspannungsfeldes näher untersucht. Im zweiten Teil der Veröffentlichung, „Anwendungen“, dienen im Schrifttum verfügbare Messdaten zu Almen-Proben der Validierung. Darüber hinaus wird der Nutzen des Kugelstrahlens am Beispiel der schwer zu beherrschenden Reibermüdung mit einer integrativen Simulation beleuchtet.
