Plane stress  plane strain using constant strain triangular elements (CST),
6 node triangular elements (LST), 4 node quadrilateral elements (Q4), and 8node
quadrilateral elements (Q8).
Also, axisymmetric plane stress using
constant strain triangles (CST_axisym).
All of this scripts use an input files
structure contained in a Excel spreadsheet with
8 work sheets defining the parameters of the
problems:
 Plane stressstrain: 1
for plane stress or 2 for plane strain
 Coordinates: x
and y coordinates for each node
 Connectivity: nodal
values for i, j, and m
for each element
 Forces: x and
y values for nodal forces
 Boundary: x
and y displacement boundary
condition (1 for fixed and 0 for free)
 Thickness: values for
thickness of each element
 Elasticity: value for
modulus of elasticity E for each
element
 Poisson: value for
v for each element
Displacements and stresses are printed into
the input Excel spreadsheet. Below are the
results for the CST solution using 2 element for
the lane stress problem given on page 364 of
Logan's "First Course in the Finite Element
Method" 6^{th} edition.
