Abstract
This research investigates the meshing of components for use in crack propagation simulations, with a focus on analyzing fracture energy and force-displacement behavior. High-quality meshes were generated and used to simulate the progression of cracks under mechanical loading. A key innovation in this work is the implementation of heterogeneous material properties within a single mesh, allowing nodes to represent different materials. This approach enables a more detailed and flexible evaluation of how varying material compositions influence fracture behavior. Multiple materials were tested within the same mesh framework to assess their individual and combined effects on simulated fracture performance. As an initial step toward applied biomedical research, this methodology is being extended to study the structural behavior of hip prostheses. The aim is to eventually inform improved prosthetic designs by simulating realistic crack propagation scenarios under complex material conditions. While this application is in its early stages, the groundwork laid by this study provides a strong basis for future biomechanical optimization and testing.
