## Summary

Abstract: This study delves into investigating the impact of temperature on the yield strength of aluminum thin films through a comprehensive analysis utilizing discrete dislocation dynamics (DDD) simulations. The researchers considered variations in DDD parameters with temperature and utilized molecular dynamics and three-dimensional simulations to reference existing experimental data. Results showed an 18% decrease in yield strength as temperature increased from 100 K to 600 K. This approach highlights the importance of considering varying DDD parameters and offers valuable insights into deformation mechanisms at elevated temperatures in materials science.
