Directories

This directory contains 3 Folders with several subfolders:



Calibration






Split into two subfolders by material type.




Each folder has the following:



python3 "Polypropylene/TPU"_Experiments_monotonic_cyclic.py - Run to generate requisite experimental plots and their pdfs.

loadCase_ParaValues_"PP/TPU"_cube.py - Library of parameter values (No output).

runCaseScript_"PP/TPU"_cube.py - This is base input file fully parametrised (No output).

python3 runScript_"PP/TPU"_cube.py - MAIN file to run and generate "dat" files and folders with the calibration results.



Creates "dat" binary files for deformation (F)/ material parameters (M)/ stress (P)/ temperature (T)/ equivalent plastic strain (epl)/ loadcase (L)

Also, Creates folders for each case to postproc in gmsh if required.)



python3 makePlots.py - Run to generate the calibration exp. vs num. plots and their pdfs based on existing results.

The other files if any include data for cyclic loading.






Experiments




The requisite experimental data for calibration and validation on PP BJ380MO by Leartiker and TPU EOS 1301 by IMDEA/JKU

Several subfolders - split first on material type and then the last folder contains a readMe.txt to explain the experiment files.

THIS FOLDER HAS NO PLOTS, only data. USE python3 "...Experiments..." .py in the other folder to generate these plots.




Validation - All validation tests for TPU split by test type and simulation numbers as follows in respective folders:




Compression - Uses TPU tests - A_viii, A_ix, A_x, A_xi

Tension - Uses TPU tests - A_iii, A_iv, A_v, A_vi

Torsion - F22, F23, F24 with axial displacement constraint, F25, F26, F27 without axial displacement constraint

TorsionRotationCorrection - F26 (w/o correction), F43 (with correction)

Images_Paper1 - Has the generated figures



Run to generate the validation exp. vs num. plots and their pdfs based on existing results: python3 validationPlots.py
