Supplemental data for "Thermo-plastic Nonuniform Transformation Field Analysis for eigenstress analysis of materials undergoing laser melt injection"

This repository contains supplemental data for the article "Thermo-Plastic Nonuniform Transformation Field Analysis for Eigenstress Analysis of Laser Dispersed Materials," submitted to Computer Methods in Applied Mechanics and Engineering (CMAME) by Felix Fritzen, Julius Herb, and Shadi Sharba.
The data contained in this DaRUS repository act as an extension to the GitHub repository <a href="https://github.com/DataAnalyticsEngineering/ThermoNTFA">https://github.com/DataAnalyticsEngineering/ThermoNTFA</a>.
Data is generated using thermo-elasto-plastic simulations on the microscale at select temperatures. Based on that, a reduced basis consisting of plastic modes is computed. Additional linear-elastic simulations are performed to determine self-equilibrated fields at select temperatures. Based on the generated data, we perform interpolation to arbitrarily many intermediate temperatures based on a method published in our recent paper <a href="https://doi.org/10.1007/s00419-023-02411-6"> "Reduced order homogenization of thermoelastic materials with strong temperature-dependence and comparison to a machine-learned model"</a>. Using the temperature-interpolated data, the NTFA system matrices are computed and stored as tabular data. This tabular data is the basis for our thermo-mechanical NTFA UMAT, which is published in the GitHub repository.
The microstructure is defined with a representative volume element (RVE) with periodic boundary conditions. Further details are provided in the README.md file of this dataset, in our manuscript and in our GitHub repository.
