Abstrakt:	Finite element analysis may not be the only method by which bone fracture initiation and propagation may be analyzed. This study compares fracture patterns generated from compression testing of bone to fracture patterns generated using a combination of both the finite element method (FEM) and discrete element method (DEM) as defined by the finite discrete element method (FDEM). Before testing, a three-dimensional bone model was developed using CT. Force and displacement data were collected during testing. The tested specimen was reimaged using CT. The solid model was discretized and material properties adjusted such that finite element-discrete element macro behavior matched the force-displacement data. A qualitative comparison of the fracture patterns demonstrates that FDEM can successfully be used to simulate and predict fracturing in bone, with this study representing the first time this has been done and reported. Competing Interests: Irazu 4.0 software to model bone fracturing in the study and was a software package that was created by Geomechanica incorporated. Pretest Scanning: SOMATOM Definition Flash computed tomography scanner used within the study was created by Siemens. Simpleware software was used in the study and was created by Synopsys incorporated. Trelis 17.0 was a 3-dimensional modeling software that was created by csimsoft. Post Test Scanning: inspeXio SMX-225CT FPD Plus is an industrial computed tomography scanner used within the study created by by the Shimadzu Corporation. (Copyright © 2022, Hudyma et al.)
