An adaptive algorithm to build up sparse polynomial chaos expansions for stochastic finite element analysis

- G. Blatman, B. Sudret
- Mathematics
- 1 April 2010

Abstract Polynomial chaos (PC) expansions are used in stochastic finite element analysis to represent the random model response by a set of coefficients in a suitable (so-called polynomial chaos)… Expand
