Code for “Inverse parameter determination for metal foils in multifunctional composites”

Please cite the Paper if you use the code https://doi.org/10.1016/j.matdes.2023.111711

The code was tested on the CentOS Linux version using Abaqus 2019 .HF6. All of the Code was written in Python 2.

This Code allows the implementation of a complex, layered sample and evaluation in the commercial Abaqus software.

Define_and_Run_Models.py

Here your Geometrical and Simulational Parameters have to be defined.
You can choose between a Strain controlled and Force Controlled simulation and related Strain and Force amplitude.

Graphical representation of the geometrical parameters used in the simulation:

The Folder “Codes” includes the following files:

Analyse_sample.py:

Boundary_conditions.py:

Allows the implementation of periodic boundary conditions of the sample. Can implement both force and strain-controlled conditions.
Periodic boundary conditions are implemented in a way to run effectively in Abaqus (see https://doi.org/10.1016/j.matdes.2023.111711 for details)
It implements a serial connector to the model to deal with machine stiffness in an experiment.

geometry_functions.py:

material_model.py:

Here your material model can be defined. Currently, published (rounded) model parameters extracted from the paper (https://doi.org/10.1016/j.matdes.2023.111711) are implemented.
Allows to implement orthotropic material parameters and checks if they are valid input parameters

meshing.py:

Generates a mesh for the sample, including parameters to define the seeds for foils and substrated differently.

run_simulation.py:

step_definition.py:

Defines the step and history output and allows the creation of time points to guarantee data analysis always at specific points (e.g. max and min amplitude)

µm UNIT System used:

LENGTH µm

FORCE µN
