Plane Stress Rectangular Parametric FEM

This model is description parametric rectangular plane stress finite element model.The element has length "a", width "b",and constant thickness "th". Each of the per corners is assumed to posses two degress of freedom displacements "u" and "v" in the "x" and "y" directions,respectively.
Thus this element possesses has nodal forces (force pairs of Fx and Fy) and total nodal displacements or nodal degrees of freedom (node*2 pairs of u and v).Also ,in the finite element as select formulation method ,an important step is to assume the pertinent displacement interpolation functions ,usually of lineer degree polynomial format.

This models, zip files components is partial parametric and fullparametric models. Only parametric model has parametric integration , transform to numerical integration method. This method is selected Gauss_Legendre.
