help Rec12
ABAQUS stress invariant output to MATLAB
Syntax
#Rec# = Fil2str('*.fil');
#out# = Rec12(#Rec#)
Description
Read stress invariant output from the results (*.fil) file generated
from the ABAQUS finite element software. The asterisk (*) is replaced
by the name of the results file. The record key for stress invariant
output is 12 (only in ABAQUS/Standard). See section "Results file
output format" in ABAQUS Analysis User's manual for more details.
The following options with parameters have to be specified in the
ABAQUS input file for the results (*.fil) file to be created and to
contain stress invariant results:
...
*FILE FORMAT, ASCII
*EL FILE
SINV
...
NOTE: The results file (*.fil) must be placed in the same directory
with the MATLAB source files in order to be processed.
Input parameters
#Rec# (string) is an one-row string containing the ASCII code of the
ABAQUS results (*.fil) file. It is generated by the function
Fil2str.m.
Output parameters
#out# ([#n# x 7]) is a double array containing the attributes of
the record key 12 as follows:
Column 1 – Mises stress.
Column 2 – Tresca stress.
Column 3 – Hydrostatic pressure.
Column 4 – Currently not used.
Column 5 – Currently not used.
Column 6 – Currently not used.
Column 7 – Third stress invariant.
where #n# is the number of elements multiplied by the number of
integration points multiplied by the number of section points
(for shell, beam, or layered solid elements) multiplied by the
number of increments. If the results file does not contain the
desired output, #out# will be an empty array
