Abstract

In this paper, we employ non-sampling techniques for numerical simulation of vibroacoustic problems including uncertain material parameters. The uncertain parameters are represented using the Karhunen-Loève expansion and structural stochastic responses are approximated by means of generalized polynomial chaos expansion with deterministic unknown coefficients. The non-intrusive stochastic FEM is implemented calculate the unknown coefficients by generating samples of parameters for a deterministic FEM code. The numerical procedure has this potential to use commercial FEM codes as black box to discretize the spatial deterministic space and easy to apply in complex industrial problems. Efficiency of the method in comparison with the experimental results is studied.
