Abstract

Results of the analysis of the influence of the specimen shape and grip-end length on the homogeneous strain in original gauge length are presented in the paper. All the results were obtained for the 316L austenitic stainless steel and for different cross-sections of the sheet specimens. The calculations were performed using program Abaqus/Explicit based on the finite element model (FEM) for the deformation process. Correlation between the strain distribution in the sample and such parameters as transition radius and grip-end length is presented in the paper.

Abstract

Im vorliegenden Beitrag werden die Ergebnisse aus Untersuchungen zum Einfluss der Probengeometrie und der Einspannlänge auf die homogene Dehnung in der Originalprüflänge vorgestellt. Alle Versuche wurden mit einem austenitischen Stahl 316L und bei verschiednen Querschnitten der Flachproben durchgeführt. Die Berechnungen des Verformungsprozesses wurden mittels der Finite-Elemente-Methode unter Nutzung des Programms Abaqus/Explicit ausgeführt. Es werden die Korrelationen zwischen der Dehnungsverteilung in den Proben und verschiedenen Parametern, wie zum Beispiel dem Übergangsradius und der Einspannlänge, beleuchtet.
