Sažetak
The probabilistic approach to welded joints design is presented and methods for their fatigue life prediction are suggested. The explicit formula for estimation the mean value of fatigue life for welded joints subjected to random loading causing in the critical point of weld toe stresses with certain stress history distributed after Weibull law, is obtained. For the first time, the unique and explicite formula for estimation the fatigue life of pre-stressed welded joints subjected to acting of stress spectrum corresponding to stationary gaussian random process, is derived in this paper, by means of results of constant amplitude test. Some directions to fatigue design approach of marine welded structures are given.
