The present study aims to compare the nodal stresses for Gauss
Quadrature method and alternate method. The alternate method represents the
corner point and midpoint of a quadrilateral as a sampling points of the
element. It is extrapolated using Richardson extrapolation in the finite
element analysis. To investigate the influence of material property variation
like Young?s modulus, numerical example for the family of quadrilateral element
(Q4 and Q8) are solved and compare the results of functionally graded elements
with the homogeneous elements. The result of nodal stresses of the alternate
method are compared to the conventional Gauss Quadrature method. - See more at:
