Reliability function is defined under suitable assumptions for dynamic stressstrength scenarios where strength degrades and stress accumulates over time. Methods for numerical evaluation of reliability are suggested under deterministic strength degradation and cumulative damage due to shocks arriving according to a Poisson process using simulation method and inversion theorem. These methods are...

It has been recognized that design-for-reliability (DFR) during the conceptual design stage is very challenging. There are several gaps and deficiencies hindering the DFR implementation. The first gap is due to the disconnection between the output of the conceptual design and reliability parameters needed for the reliability modeling. The second gap is between the knowledge available during the...

Cascade reliability model is a special type of Stress Strength model. The n Cascade system is a h ierarch ical standby redundancy system, where the standby component taking the place of failed component with decreased value of stress and independently distributed strength. This paper deals with the generalized exponential distribution with cascade system.

By taking the axial tension member as an example, the damage caused by the cyclic stress influencing reliability was researched. According to the damage mechanics theory, some micro-cracks were observed in the material with cyclic load. With the increase of times loads inflicting, the fresh micro-cracks were formed; meanwhile, the existing cracks further extended, consequently, the effective be...

In many real life scenarios, system reliability depends on dynamic stress-strength interference, where shocks appear at random time points and the strength of a system varies over time. The resulting life distributions exhibit decreasing, increasing, upside-down and bathtub failure rate depending on the nature of strength function. This class of life distributions is useful for reliability anal...

A new approach to structural reliability analysis under incomplete information about the stress and strength in the form of intervals provided by experts or obtained as a result of imprecise measurements is proposed in the paper. The approach takes into account the possible fact that the number of judgments or observations may be rather small. It is shown that interval-valued information about ...
