Inner design of artificial test bones for biomechanical investigations using topology optimization

Abstract Artificial or human test bones are used for the biomechanical testing of implants. Human rare and not always available. These must, therefore, be substituted with artificial bones. However, current only available specific characteristics (e.g., age groups disease characteristics). Additionally, their mechanical properties comparable to a limited extent those bone. This paper presents methodology designing additively manufactured that replicate behavior Topology optimization methods generate bone's internal structure. The geometric model is based on computed tomography dataset input data can manipulated in advance reproduce defects patterns. bone was fixed at distal diaphysis loaded different forces topology optimization. Boundary conditions due possible additive manufacturing processes were incorporated into ensure manufacturability. result compared experimental from A bone-like structure increased compliance topology-optimized commercial observed.
