A generalized isogeometric boundary element method for the uncertain analysis of infinite domain two-dimensional acoustic problems

Yan Yang,

Xiaohui Yuan
et al.

Abstract: The key aim of this paper is to provide a new nth generalized order perturbed isogeometric fast multistage technique of boundary elements to compute the propagation of time harmonics in an infinite region. Structural geometry and boundary integral equations are constructed by using non-uniform rational B-splines. The source of system uncertainty is believed to be the incident plane wave number’s unpredictability. The actual field, depending on the input random variables, is simulated using the extended nth-ord… Show more
