Supporting data for "Integrated optimization design framework for metallic orthopedic devices with graded-density lattice microstructures"

My research project is to establish a integrated optimization design framework for metallic orthopedic devices with graded-density lattice microstructures. The framework can adjust the material density distribution in side common orthopedic devices such as femoral implant and spinal cage, so as to redistribute the stress distribution in bone tissue anc moderation bone degeneration problem. The frameworks consists of 3 parts: Firstly, a data-driven mechanical property homogenization system is established for anisotropic lattice microstructures. secondly, multi-scale topology optimization is conducted on femoral implant with anisotropic microstructures. Thirdly, topoloyg optimization is conducted on spinal cage with isotropic graded-density lattice microstructures.

The supporting data uploaded are corresponding to the framework structure. Folder1 (kernal) includes basic python Class files and program tool files shared by all 3 functional parts.

 Folder 2 (femur) includes the source codes, training samples, iteration files and output documents for Gaussian process machine learning and topology optimization, performance evaluation and model reconstruction of lattice femoral implants. Due to the upload file size limit, the source codes and training samples for lattice unit cell failure cirteria are saved in Folder 3 (failure) and source codes and iteration files of femoral implants are saved in Folder 4 (main_iteration).

Folder 5 (spine) includes source codes, iteration files and output documents for topology optimization, performance evaluation and model reconstruction of lattice spinal cage with non-eccentric, flexion, extension and lateral bending loading conditions. Due to the upload file size limit, the source codes and iteration files of non-eccentric and flexion cases are saved in Folder 6 (main_iteration_1) and the source codes and iteration files of extension and lateral bending cases are saved in Folder 7 (main_iteration_2).

Folder 8 (figure_table) includes all figures and tables appeared in the thesis draft. The soruce file of the figures and tables are recorded in the README.txt in the folder.
