Applied Mathematical Modelling, 2014 Abstract This paper investigates the formability and forming limit curve of aluminium alloy sheet of grade Al 1350 with respect to annealing temperature and strain conditions through statistical approach. The uncertainty of forming limit curve (FLC) due to anisotropy parameter and strain hardening exponent have also been taken into consideration. The

Reliability sensitivity analysis based on multi-hyperplane combination method
Defence Technology, 2014 For a nonlinear limit state function, the first-order reliability method (FORM) may cause large errors in the computation of not only the reliability index or failure probability but also the reliability sensitivity.

Reliability analysis method based on KL expansion and its application
Yantu gongcheng xuebao, 2020 The spatial variability is an inherent attribute of soil properties. To consider the influences of spatial variability of soils on the reliability of geotechnical engineering, a KL-FORM and a KL-RSM are proposed, in which the Karhunen-Loeve expansion ...
