Abstract
New possibilities of low cycle fatigue material properties testing with the use of micro-specimens are presented in this publication. The discussed solution is of great significance for analysis of local properties of a material, e. g. in welded structures. Properties of a material determined in the manner presented in this publication find application both in fatigue life assessment (fatigue life curves) and in material modeling (cyclic stress-strain curves), e. g. in numerical analysis of local strain and stress that occur in structural components.
