Reliability assessment of composite structures with multiple failure modes

Civil-Comp Proceedings, 2010
The introduction of reliability assessment methods in safety analysis of composite structures increased the complexity and the efficiency of failure evaluation methodologies proposed in the literature. In this paper, an approach based on surrogate modelling of first ply failure to obtain the reliability of the whole composite structure is proposed and ...

Reliability Analysis of Mechanical Component with Multiple Failure Modes

Transactions of the Korean Society of Mechanical Engineers A, 2013
Most products are indeed governed by multiple failure modes. However, there are few cases in which reliability analysis applies to only one failure mode at a time. Furthermore, reliability data do not include information about failure modes, or the reliability analysis is performed using a representative failure mode.

STRUCTURAL SYSTEM RELIABILITY UNDER MULTIPLE FAILURE MODES

34th Structures, Structural Dynamics and Materials Conference, 1993
This paper describes a computational method for system reliability estimation of propulsion structures. The failure domain of the entire structural system is computed through the union of failure regions for various critical system failure modes. The effect of non-critical progressive damage is incorporated through structural reanalysis, resulting in ...

Multiple Modes of Electromigration Failure in SAC Solder Alloys

2018 International Integrated Reliability Workshop (IIRW), 2018
The anisotropic nature of tin, the principle component of Pb-free solder, can cause significant variations the physical characteristics of the solder bumps. Grain size and orientation in a solder bump can drastically change the properties of one bump, giving rise to multiple potential failure modes between bumps.

Analysis of two-machine lines with multiple failure modes

IIE Transactions, 2002
This paper presents an analytical method for evaluating the performance of production lines with a finite buffer and two unreliable machines. Unlike in earlier papers, each machine can fail in more than one way. For each failure mode, geometrically distributed times to failure and times to repair are specified.

Reliability analysis of retaining walls with multiple failure modes

Journal of Central South University, 2013
In order to reduce the errors of the reliability of the retaining wall structure in the establishment of function, in the estimation of parameter and algorithm, firstly, two new reliability and stability models of anti-slipping and anti-overturning based on the upper-bound theory of limit analysis were established, and two kinds of failure modes were ...

An efficient surrogate model for system reliability with multiple failure modes

Quality and Reliability Engineering International
AbstractThe failure modes of complex systems are often highly dependent. Aiming at the reliability analysis of engineering systems with multiple failure modes, an efficient surrogate model for system reliability with multiple failure modes is proposed, namely, the Copula Adaptive Kriging surrogate model (CAKSM).

Efficient surrogate models for reliability analysis of systems with multiple failure modes

Reliability Engineering & System Safety, 2011
Abstract Despite many advances in the field of computational reliability analysis, the efficient estimation of the reliability of a system with multiple failure modes remains a persistent challenge. Various sampling and analytical methods are available, but they typically require accepting a tradeoff between accuracy and computational efficiency.

A compositional method for reliability analysis of workflows affected by multiple failure modes

Proceedings of the 14th international ACM Sigsoft symposium on Component based software engineering, 2011
We focus on reliability analysis for systems designed as workflow based compositions of components. Components are characterized by their failure profiles, which take into account possible multiple failure modes. A compositional calculus is provided to evaluate the failure profile of a composite system, given failure profiles of the components.

Multiple failure modes prognostics using logical analysis of data

2015 Annual Reliability and Maintainability Symposium (RAMS), 2015
In this paper, we propose a multiple fault prognostic methodology which considers the condition monitoring data collected from equipment that experiences one of several different failure modes over its life span. The methodology is based on the exploitation of historical data for knowledge extraction and representation in the form of relevant patterns.
