Description

The main results are in folders Population1 and Population2 (that correspondes to initial Popolation 1 and 2, respectively). Each of them contains 3 folders with the results for the investigated cases). The other two folders contain the sensitivity analysis and analysis of the influence of friction. In order to run the simulations one has to first have Wolfram Mathematica with the AceFEM package installed. Running each optimization is possible using the EA.nb file. Running the sensitivity analysis is possible using the Sensitivity.nb file. In order to run the friction analysis one has to run virgin.nb file for each firction coefficient value. Analysis of the results is possible using the Podsumowanie.nb file in each folder. There are several codes used to conduct the simulations. In case of using the contact code one should cite Kucharski, S., S. Stupkiewicz, and H. Petryk. "Surface pile-up patterns in indentation testing of Cu single crystals." Experimental Mechanics 54 (2014): 957-969. In case of using the hanging nodes formulation one should cite: Frydrych, Karol. "Crystal plasticity finite element simulations of the indentation test." Comput. Methods Mater. Sci 19 (2019): 41-49. In case of using the crystal plasticity code one should cite: Kucharski, S., S. Stupkiewicz, and H. Petryk.
