Influence of geometry on stress state in bulk characterization tests
This paper is concerned with the selection of the geometries of test specimens for bulk metal characterization tests. Simulations of characterization tests on cylindrical, notched, and shear specimens were conducted to allow for the analysis of stress state evolution during the tests and to evidence the impact of geometry on stress state. Both stress triaxiality and Lode parameter were considered for selecting representative specimens. Three choice criterions were regarded: the diversification of stress states as well as the constancy and the nearness of stress state indicators to the theoretical values along the deformation.
