TL;DR: In this paper, the Kriging model approach for stochastic free vibration analysis of composite shallow doubly curved shells is presented. And the convergence studies and error analysis are carried out to ensure the accuracy of present approach.

TL;DR: In this paper, a nonintrusive Gram-Schmidt polynomial chaos expansion (GPCE) method is adopted in uncertainty propagation of structural uncertainty to dynamic analysis of composite structures, when the parameter uncertainties represented by fuzzy membership functions are mapped to a zone of output data with the parameters determined by D-optimal design.

TL;DR: In this article, a generic random sampling-high dimensional model representations (RS-HDMR) approach for free vibration analysis of angle-ply composite plates is presented, where a metamodel is developed to express stochastic natural frequencies of the system, and sensitivity analysis is carried out to address the influence of input random parameters on output natural frequencies.

TL;DR: In this article, a generic multivariate adaptive regression splines-based approach for dynamics and stability analysis of sandwich plates with random system parameters is presented, where the propagation of uncert...

TL;DR: In this article, the effect of noise on surrogate-based stochastic natural frequency analysis of composite laminates is explored. But, the proposed approach is general in nature and therefore it can be extended to explore other surrogates under the influence of noise.
