Summary

Objectives of our paper are as follows:

Giving a brief overview on the most relevant life assessment models for low cycle fatigue (LCF); determining the plastic strain work by two measuring methods, i.e. calculating the hysteresis loop energy for each individual cycle (Wp,e) and for the so called representative cycles (Wp,r); comparing the plastic strain energy values if determined by measurement or calculated using empirical relationships.
