This study represents an in-depth exploration of stress distribution within polymethylmethacrylate (PMMA) orthopedic cement, a critical material used in hip prostheses. Focusing on the inherent fragility of the cement and its intricate interface with implants, our research meticulously investigates stress patterns surrounding individual cavities. What sets this study apart is its nuanced examination of interactions between multiple cavities and their consequential effects on both stress intensity and distribution. The findings from this research offer nuanced and illuminating insights into the interconnected nature of cavities, aligning closely with observations derived from real-world experiments. This study significantly advances our understanding of potential damage phenomena within total hip prostheses. Moreover, it establishes a robust foundation for potential advancements in the design and performance of prostheses, taking into account the complex interplay within orthopedic cement. These insights pave the way for more targeted improvements in the mechanical behavior of hip prostheses, thereby contributing to the ongoing evolution of orthopedic implant technology.
