Stochastic multi-scale finite element based reliability analysis for laminated composite structures (2017)
Journal Article
Zhou, X.-Y., Gosling, P. D., Ullah, Z., Kaczmarczyk, L., & Pearce, C. J. (2017). Stochastic multi-scale finite element based reliability analysis for laminated composite structures. Applied Mathematical Modelling, 45, 457-473. https://doi.org/10.1016/j.apm.2016.12.005

This paper proposes a novel multi-scale approach for the reliability analysis of composite structures that accounts for both microscopic and macroscopic uncertainties, such as constituent material properties and ply angle. The stochastic structural r... Read More about Stochastic multi-scale finite element based reliability analysis for laminated composite structures.
