Failure assessment of reinforced rock slopes subjected to bolt corrosion considering correlated multiple failure modes

, 2021
This paper presents a reliability-based methodology for failure assessment of reinforced rock slopes subjected to bolt corrosion. Strength failure of the rock bolt, bond failure between the rock bolt and the grout and bond failure between the rock and ...

Statistical Analysis of Linear Degradation and Failure Time Data with Multiple Failure Modes

Lifetime Data Analysis, 2004
The paper considers linear degradation and failure time models with multiple failure modes. Dependence of traumatic failure intensities on the degradation level are included into the models. Estimators of traumatic event cumulative intensities, and of various reliability characteristics are proposed.

Multiple failure mode and effects analysis - an approach to risk assessment of multiple failures with FMEA

Annual Reliability and Maintainability Symposium, 2005. Proceedings., 2005
By integrating the procedures of the FMEA method (failure mode and effects analysis) and the FTA method (fault tree analysis) into a combined procedure, the mFMEA (multiple failure mode and effects analysis), an inclusive reliability analysis of complex, mechatronical systems, is made possible.

On the linear degradation model with multiple failure modes

Journal of Applied Statistics, 2010
The purpose of this work is to develop statistical methods for using degradation measure to estimate a survival function for a linear degradation model. In this paper, we review existing methods and then describe a parametric approach. We focus on estimating the survival function.

Structural Expected Lifetime Estimation for Systems With Multiple Failure Modes Based on Adaptive Learning Kriging Models

IEEE Transactions on Reliability
Structural safety is a critical concern when dealing with uncertainty, and the expected lifetime is an essential metric for its quantification. Physics-driven methods offer adequate simulation data in the initial design stage, eliminating the requirement

Uncertainty Quantification In The Prediction of Remaining Useful Life Considering Multiple Failure Modes

ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, Part B: Mechanical Engineering
Despite the substantive literature on remaining useful life (RUL) prediction, less attention is paid to the influence of epistemic uncertainty and aleatory uncertainty in multiple failure behaviors in the accuracy of RUL.

The impact of multiple failure modes on estimating product field reliability

IEEE Design & Test of Computers, 2006
A difficulty in reliability modeling is how to capture the impact of all of the various reliability defect types. The general approach to optimizing burn-in that we describe in this article addresses a multiple-defect environment. The approach has four main parts: (i) modeling the product's failure rate distribution, (ii) establishing the Pareto ...

System Reliability Assessment for a Rock Tunnel with Multiple Failure Modes

Rock Mechanics and Rock Engineering, 2012
This paper presents a practical procedure for assessing the system reliability of a rock tunnel. Three failure modes, namely, inadequate support capacity, excessive tunnel convergence, and insufficient rockbolt length, are considered and investigated using a deterministic model of ground-support interaction analysis based on the convergence–confinement

Degradation Estimation of Electro-Mechanical Actuator With Multiple Failure Modes Using Integrated Health Indicators

IEEE Sensors Journal, 2020
Electro-Mechanical Actuator (EMA) is a key component in the flight control actuation of the more electric aircraft. The degradation of EMA has a significant influence on its performance. Hence, the degradation estimation of EMA needs to be studied, which
