Abstract
The paper describes the problem of fatigue life assessment for the case of explosive cladded transition joints under random loading. Such elements are usually used in the lightweight automobile industry as well as in the marine industry. Due to this, they are undergoing random loading conditions in terms of road surface quality and the change of sea waves. The literature presents two domains in which one can approach this problem, which are the time domain and the frequency domain. The presented algorithm takes into account the residual stress effects which appear during the welding process in the form of the mean stress compensation with classical models such as the Gerber model. It also takes into account the effect of non-Gaussian loading by providing additional correction methods. The discussion on the use of strictly frequency domain estimates is provided and a number of probability density functions is presented.
