On the basis of the method of FMECA and the theory of fuzzy sets and the method of fuzzy composite evaluation, this paper advanced a new method of system reliability analysis i.e. Failure Model Effect Fuzziness Analysis (FMEFA), and discussed the method of FMEFA by the reliability analysis of the sugar cane crusher system for example.
(NO. 02JSNJYZ101001) and natural science foundation of Jiangsu (NO.BK2001098). At first, the recent research advances on the remanufacturing, the service characters and failure models, remaining life of chemical equipments are reviewed in length. Furthermore,the recent concept of remanufacturing and redesign in 3R (Remanufacturing, Redesign and Recycle) modes are applied in chemical equipment.
After confirming the failure models of the structure and the probability distributing of the stochastic variable, we could use Monte Carlo Method and Response Surface Method doing reliability analysis of the bridge.
An analytical procedure, based on the limit failure mode and ductility, was presented to predict the applied area of CFP.
Failure mode, stress distribution, plastic-zone development and ultimate load capacity of the joints were investigated, and effects of the ring stiffeners on the joint behavior were observed through the experiments.
The main failure mode of CFRP-strengthened beam is the intermediate crack-induced debonding of CFRP laminates, provided that the development length of CFRP laminates and shear capacity of the beam are sufficient.
The structural response throughout the loading regime was captured in terms of the load-deflection behaviour, which in addition to the post-peak response characterized the failure mode of the test beams.
Angular displacements of armature under different sinusoidal vibration conditions are solved in order to obtain the failure mode result from armature system.
It was found that the inclination angles and loading positions have an obvious effect on compression ultimate load-carrying capacities and failure modes.
All three sections have certain post-buckling strength, and the failure modes of most of the specimens contained distortional buckling.
The experimental results showed that the consumption of CFP had significant effects on failure modes and the flexural capacity.
Further, attention should be paid to the research on the failure modes and criterions of high concrete dam failure analysis and safety evaluation, and the effect of uncertainty and classification of safety should be considered too.
The failure modes of every element of the structural system are analyzed under dead and fatigue loads, and the influence of the correlation of failure modes on reliability of the element is considered.
We studied the development of ventricular tachyarrhythmias using programmed stimulation in a pacing-induced heart failure model.
A rate-dependent bond failure model qualitatively describes the above process, in which the activation energy of bond dissociation is assumed to be a time-dependent parameter.
A bond failure model was proposed in which fracture takes place along the non-connected regions, with cohesive failure in the foamed areas.
Test results on adhesive joints from the literature are analysed and compared with the new adhesive joint failure model based on the two well-established fracture mechanics models developed for other material systems.
5/6 subtotal nephrectomy was performed to establish chronic renal failure model.
Indeed, Bayesian inference of a nonhomogeneous Poisson process with three different failure models (linear, exponential, and power law) were considered, and the effects of the scale factor and the aging rate of these models were investigated.
As for other materials, wood fracture and failure models always require some degree of experimental calibration, which can introduce ambiguity into numerical predictions because at present there is a high degree of inconsistency in test methods.
In the algorithms for the failure-by-omission and Byzantine failure models, each processor attempts to identify the faulty processors and corrects values transmited by them to reduce the amount of disagreement.
We then analyze these problems in terms of common knowledge in several failure models.
