Isoparametric Triangular Plane Stress FEMs

Isoparametric triangular

Description

This model is description isoparametric triangular plane stress finite element model.The element has constant thickness "th" and other dimnesion not need. 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 isoparametric plane stress triangular finite element models. This models is control the sap2000 (Stuructral analysis program) and other analysis results collocated.
