Sažetak
Fatigue life od specimens made of AlMg4.5Mn aluminium alloy is analized. Specimens of parent metal, specimens with butt welded joints and specimens with cruciform welded joint are used. Experiments are performed at two level block-program tests with different spectrum densities, based on aproximation of Gaussian normal distribution. Based on experimental results, S-N curves are defined, by which the fatigue life of welded joints is presented in wide range - from constant amplitude loading to spectrum loading with low spectral density. The method for fatigue life prediction based on experimental results is proposed. This method is verified by performed experiments and by comparison to the literature, it showed very good results, and it is suitable for practical use because of few experimental data that are required.
