Abstract: This paper describes the use of meshfree methods for response and design sensitivity calculations within structural reliability analysis when geometric shape is a random variable. Brief descriptions of meshfree methods and advanced probabilistic methods are provided. An existing interface between the probabilistic analysis and traditional finite element method is modified to allow the use of meshfree methods for response and design sensitivity calculations within the probabilistic analysis routine. Three examples that treat design shape and thickness as random variables are presented to assess the accuracy and use of meshfree methods for reliability analysis.
Keywords: meshfree methods; probabilistic analysis; structural reliability analysis; shape design sensitivity; reliability based design optimisation; RBDO; vehicle design; automobile industry; automotive design.
