ABSTRACT
The principal objective of this work is to evaluate and test the strain based sector elements for the
analysis of plane elasticity problems with circular contour.
We present some sectors elements with five nodes; have two degrees of freedom (displacements radial
Ur and circumferential Vθ ) per node, where the static condensation method was applying to condense
their internal nodes.
The effectiveness of these elements is tested by its applications in problems of the symmetrical
rotational deformations of the plates with circular contours. It is shown that the strain based sector
elements converge much better than those based on displacements, and that requires a minimum
number of elements on which plate is divided.
