In the paper, based on the results of experimental research on the behavior of samples in the form of
round smooth test specimens (STS) made of high strength low alloy steel (HSLA), Nionikral 70 (NN
70), under conditions of low cycle fatigue (LCF), a computational stress analysis was performed
using numerical methods.
Experimental investigations of the behavior of the samples were performed with controlled and fully
reversible deformation ( /2 = const, R = min/ max = 1), according to the ISO 12106:2003 (E)
standard.
For computational analyses, the method of least squares (in the Excel program) and the finite
element method (FEM) (in the SolidWorks program) were used. The behavior of HSLA steel during
low cycle fatigue (LCF) simulation was analyzed in the Cosmos module of the SolidWorks program.
On the basis of the analysis of the results of the stress deformation state and the determination of the
life span through the isolines of the life span and comparison with the result...s of experimental tests, a
graphic representation is given. Specific load cycles involving the entire round smooth test specimen
ligament for a specific load in a wide range of LCF loads were analyzed.
The analyzes showed the justification of the effort to solve the life assessment of steel subjected to
low cycle fatigue (LCF) numerically. The results of experimental tests and simulation tests also gave
us important data on understanding the LCF behavior of HSLA steel NN 70.
