Abstract
A mixed finite element is presented with an isoparametric formulation in the natural plane
(ξ,η).This element extended for the analysis of the bending functionally graded beams under static loads. The Parameters of beams like Young’s modulus and Poisson’s ratio are
changing through the thickness direction as a power-law distribution. The results obtained
by the present mixed finite element are presented and compared with analytical and numerical solutions obtained in the literature.
The present element is also proposed to analyze kinking crack in functionally graded materials. Quasi-static crack propagation under mode 1, and the mixed-mode is performed
for the homogenous and functionally graded plate under uniform axial tension. The results
obtained by the present mixed finite element presented and compared with previous experimental and numerical obtained by finite element software in the literature. Where the
present element proven a good results with the fewer elements and lower computational
effort.
