On the approximation in the smoothed finite element method (SFEM)
TL;DR: In this paper, the authors proposed a systematic approximation scheme based on non-mapped shape functions, which both allows to fully exploit the unique advantages of the smoothed finite element method (SFEM) and resolve the existence, linearity and positivity deficiencies pointed out in (Int. J. Numer.

TL;DR: In this paper, an extended finite element formulation for dynamic fracture of piezo-electric materials is presented in the context of linear elastic fracture mechanics and applied to mode I and mixed mode-fracture for quasi-steady cracks.
Journal ArticleDOI
Dynamic instability analysis of sandwich plates with CNT reinforced facesheets
TL;DR: In this article, the dynamic instability characteristics of sandwich panels with carbon nanotube (CNT) reinforced facesheets subjected to in-plane periodic load is investigated using a shear flexible QUAD-8 serendipity element.
Journal ArticleDOI
Analysis of functionally graded material plates using triangular elements with cell-based smoothed discrete shear gap method
Sundararajan Natarajan,António Ferreira,António Ferreira,Stéphane Bordas,Erasmo Carrera,Erasmo Carrera,Maria Cinefra,Ashraf M. Zenkour,Ashraf M. Zenkour +8 more
TL;DR: In this article, a cell-based smoothed finite element method with discrete shear gap technique is employed to study the static bending, free vibration, and mechanical and thermal buckling behaviour of functionally graded material (FGM) plates.
Journal ArticleDOI
A parametric study on the buckling of functionally graded material plates with internal discontinuities using the partition of unity method
TL;DR: In this article, the effect of local defects, viz., cracks and cutouts on the buckling behavior of functionally graded material plates subjected to mechanical and thermal load is numerically studied.
