Reliability and quality of product is not established completely in detail design process, but is brought out essentially in the course of conceptual design. Flow and operation are the two basic element of function structure network. The failures of flow and operation will transfers in function structure network. Failure analysis is an important technology in product reliability and quality??s guarantee...
The traditional reliability methodology considers the failure time of product is uncertain, and the probability is used to express the failure of product. The current reliability methodology considers the uncertainty is occurred in failure-process of product, and the failure-process analysis is concerned more than failure-time analysis. In this situation, we propose the technique of Integrating Design...
We explore reliability-based designs of isogrid stiffened panels. Uncertainties in material properties and geometric manufacturing uncertainties are represented by random variables. Due to the multiple failure modes in the stiffened panels, polynomial response surface approximation are fit to the most critical safety margins in the panel. Probability of failure is calculated by Monte Carlo simulation...
