Opis

This book deals with hip replacements, a crucial area for people suffering from severe pain caused by the degradation of this joint. Implantation of prostheses can relieve pain and restore mobility, but despite advances in materials and techniques, challenges persist, including femoral stem fracture and component wear. Research focuses on improving the performance and durability of implants, particularly through the use of biomaterials more adapted to the human body. This book explores the causes of femoral stem cracks and fractures, highlighting numerical modeling as a complementary method to physical experimentation. This method makes it possible to simulate the complex movements and deformations that these components undergo under dynamic stresses. The book is divided into four chapters: a presentation of prostheses, a review of research on implant fatigue, a numerical analysis with the finite element method, and finally a simulation of the polycyclic fatigue behavior using specialized software.
