In this paper, the dynamic response of a vibratory system equipped with a single-unit impact damper is analyzed. The reliability behavior of this system is investigated when the stress and strength are distributed lognormally. The standard deviation of lognormal stress is realistically calculated by applying external noise and an uncertainty parameter in the simulated model. Variations of the d...

In this paper, the stress rupture reliability of Carbon/Epoxy Composite Overwrapped Pressure Vessels (COPVs) is examined utilizing the classic Phoenix model and accounting for the differences between the design and the actual burst pressure, and the liner contribution effects. Stress rupture life primarily depends upon the fiber stress ratio which is defined as the ratio of stress in fibers at ...

In this paper, we estimate the multicomponent stress-strength reliability by assuming the Burr-XII distribution. The research methodology adopted here is to estimate the parameters by using maximum likelihood estimation. The reliability is estimated using the maximum likelihood method of estimation and results are compared using the Monte-Carlo simulation for small samples. By using real data s...

Experiments show that the strength of nanostructures can be very high and that strength statistics are dominated by surface flaws. To understand the dependence of strength on the surface morphology, a series of fracture mechanics based Monte-Carlo simulations were performed. The surfaces of previously tested Si nanobeams were measured, statistically characterized and equivalent surfaces were ge...

In many real life scenarios, system reliability depends on dynamic stress-strength interference where strength degrades and stress accumulates concurrently over time. In some other cases, shocks appear at random time points, causing damage which is only effective at the instant of shock arrival. In this paper, we consider the identifiability problem of a system under deterministic strength degr...

Generalized logistic distribution, as the generalized form of symmetric plays an important role in reliability analysis. This article focuses on statistical inference for stress–strength parameter R=P(Y<X) distribution with same and different scale parameters. Firstly, we use frequentist method to construct asymptotic confidence intervals, adopt constructing point estimators well intervals. ...
