Opis:: The aim of this paper is to propose an algorithm for fatigue life determination with the use of widely-known criteria for the fatigue life considering proper determination of material characteristics, which are a function of the number of cycles to failure. The application of the modified algorithm has been presented within the criteria of Findley, Matake, Papadopoulos and Dang Van, and the results of calculations have been compared with test results for steels S355J2G3 and Ck45. For both materials analysed, the application of the modified algorithm in the fatigue criteria makes it possible to obtain much more precise results of the calculations for all types of the loading analysed.

Opis:: The paper presents a comparison of the fatigue life curves based on test of 15Mo3 steel under cyclic, pendulum bending and tension-compression. These studies were analyzed in terms of a large and small number of cycles where strain amplitude is dependent on the fatigue life. It has been shown that commonly used Manson-Coffin-Basquin model cannot be used for tests under cyclic bending due to the impossibility of separating elastic and plastic strains. For this purpose, some well-known models of Langer and Kandil and one new model of authors, where strain amplitude is dependent on the number of cycles, were proposed. Comparing the results of bending with tension-compression it was shown that for smaller strain amplitudes the fatigue life for both test methods were similar, for higher strain amplitudes fatigue life for bending tests was greater than for tension-compression.
