Título : A robust five-unknowns higher-order deformation theory optimized via machine learning for functionally graded plates

Autor : Yarasca, J.; Mantari, J.L.; Monge, J. C.; Hinostroza, M.A.

Resumen : This article presents a new kind of higher-order deformation theory, called Parametric Higher-order Deformation Theory (PHDT), for the static analysis of functionally graded plates (FGPs). The novelty of the PHDT is the use of strain shape functions that are calibrated by ...
