Calculation of the yield and ultimate tensile strengths, elongation and Charpy toughness of ferritic steel welds made using arc welding. The inputs are chemical composition and welding conditions.
Language: | C, FORTRAN, Shell Scripts |
Product form: | Source code and executables |
Platform: | Linux |
Complete program.
bin | This directory contains models and then accessory programs |
anndata_example | File containing inputs that are to be varied. Format of this file is <base composition><minimum><maximum><step size><step (yes=1,no=0)><Input name>. |
run_models | Script to run the models. To execute type "./run_models" and press enter. Do not edit this script unless you know what you are doing. |
CHP_unsorted_RESULT.dat | File contains the predictions of Charpy impact toughness. Format of the file: <Variable stepped> <Predicted value><Error value><Prediction-error><Prediction+error>. |
YS_unsorted_RESULT.dat | Contains predictions of yield strength. File format same as CHP_unsorted_RESULT.dat. |
UTS_unsorted_RESULT.dat | Contains predictions of ultimate-tensile strength. |
ELN_unsorted_RESULT.dat | Contains predictions of elongation. |
Directories | |
acc_prog | contains accessory programs that program "run_models" script uses |
data_no.c | To read the number of input data. |
split_out.c | To split out the composition inputs for ys, uts, elongation and Charpy toughness models. Note that the oxygen and nitrogen concentrations do not affect the yield strength. Nitrogen does not affect ultimate tensile strength and elonation. Hence when varying these elements expect changes in only toughness predictions. |
ys | Directory containing yield strength model |
uts | Directory containing ultimate-tensile strength model |
chp | Directory containing Charpy toughness model |
eln | Directory containing Elogation model |
chp_RESULT,eln_RESULT,ys_RESULT and uts_RESULT | In case you have stepped more than one variable in the anndata_example file, then the results for each variable are separated and placed in this directory. |
Base value | Minimum | Maximum | Step | (1 to step and 0 not to step) | Variable name |
