a few Matlab programs for finite element - lizard - 01-01-2011

3D Solid 20-Node Element Program

This program can analyze all types of 3D continous or solid body problems with all degree of freedom using Finite Element Method with choice 20-Node Isoparametric element under any kind of concentrated nodal loadings (Fx, Fy, Fz) and submit values of nodal displacements and element stresses as MATLAB output.

Finally, to test this program, different Examples are given which in these examples program outputs compared with the results from ABAQUS or ANSYS software. Similarity of results shows that this program works without any deficiencies as well as these two softwares.

Constant Strain Triangle Element Program

This program is able to analyze all types of plane stress and plane strain problems with all degree of freedom using Finite Element Method (with choice “CST”-Constant Strain Triangle element) under any kind of concentrated nodal loadings (Fx, Fy) and submit values of nodal displacements, element stresses and strains and elements principal stress as MATLAB output.

to test the program we compare results of two examples with commercial programs.
