The main file is the ’RVE set-up file’. This is the file where input data is given for the creation of the Abaqus input file and the script file used to run the simulations. The user can choose which of the elastic properties they are interested in and provide dimensions and material properties for the tows and stitches. Stitches are created by providing the start and end-coordinate for each segment. This main file uses the ’RVE functions file’ and the ’scriptfile’ to get all the information required to write the output files. It is also responsible for setting the interactions and contact between the different set and surfaces. The ’RVE functions file’ also creates the reference points that are used to apply the strains on the RVE. Finally. this file imports the constraint functions from the ’Constraint functions file’ to create the boundary conditions necessary to ensure the deformed surfaces …
