Reliability and Sensitivity Analysis of Trusses

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000
AbstractAn approach for integrating the random nature of load with elastic‐plastic strains of the structure and calculating the reliability and sensitivity of trusses is presented. The paper contains some theoretical basis and practical proposition for solving the problem. Some numerical results are shown.

Reliability sensitivity based on first-order reliability method

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011
A new efficient and accurate method for reliability sensitivity analysis of mechanical components is proposed based on the first-order reliability method (FORM). This method provides very close approximate solutions for strongly non-linear limit state functions with independent normal random variables.

Reliability of global sensitivity indices

Journal of Statistical Computation and Simulation, 2011
Uncertainty and sensitivity analysis is an essential ingredient of model development and applications. For many uncertainty and sensitivity analysis techniques, sensitivity indices are calculated based on a relatively large sample to measure the importance of parameters in their contributions to uncertainties in model outputs.

Structural reliability and its sensitivity

Civil Engineering and Environmental Systems, 1985
Abstract The paper shows that a least-biased estimate of the failure probability of a structural component or structure with random loads and strengths may be calculated by using the maximum entropy distribution. The method permits the probability of failure to be calculated directly from statistical load and strength data without the need to choose ...

Reliability in Checking Liquid Penetrant Sensitivity

1988
Zunaechst werden die Einfluesse auf die Empfindlichkeit, die Kontrollen zu ihrer Ermittlung und die Uebertragbarkeit der Ergebnisse an Kontrollkoerpern diskutiert. Besonders wird auf die Festlegungen im Regelwerk eingegangen und herausgestellt, dass die bei Kontrollkoerpern geometrische Form und der Zustand der Risse nicht genuegend beruecksichtigt ...

Computational methods for efficient structural reliability and reliability sensitivity analysis

AIAA Journal, 1993
This paper presents recent developments in efficient structural reliability analysis methods. The paper proposes an efficient, adaptive importance sampling (AIS) method that can be used to compute reliability and reliability sensitivities. The AIS approach uses a sampling density that is proportional to the joint PDF of the random variables.

Reliability estimation and sensitivity testing

Microelectronics Reliability, 1975
Abstract Reliability requirements are sometimes expressed as that at a particular stress level, say x o , the failure probability of a device should not exceed p o . Considered here are the collection and statistical analysis of data by which one can assess whether the requirement is met.

Reliability sensitivity-based correlation coefficient calculation in structural reliability analysis

Chinese Journal of Mechanical Engineering, 2012
The correlation coefficients of random variables of mechanical structures are generally chosen with experience or even ignored, which cannot actually reflect the effects of parameter uncertainties on reliability. To discuss the selection problem of the correlation coefficients from the reliability-based sensitivity point of view, the theory principle ...
