ABSTRACT
The majority of the damage accumulation hypotheses known from literature assume that all stresses (above a certain level) somehow negatively influence the system damage, independent of the actual system’s state-of-damage, load history, and point in time when the stress is applied. Under this restrictions only a vague information about the accumulated damage (remaining lifetime) can be stated. Furthermore,
of the used math-static. This means that the information gathered under real operating conditions (observed stochastical failures,...) are not used to adapt/modify the formerly assumed hypotheses. There is no closed-loop (feedback of failure information). Hence the statements about the actual state-of-damage do not improve over the system usage (time, driven kilometers,...).
