Plane stress - plane strain using constant strain triangular elements (CST),
6 node triangular elements (LST), 4 node quadrilateral elements (Q4), and 8-node
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 stress-strain: 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" 6th edition.
