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...

This book highlights the importance of post-treatments in improving the mechanical properties of parts manufactured by laser powder melting (SLM). Through numerical simulations carried out with SIMUFACT Additive and experimental studies, it has been demonstrated that these treatments significantly influence the strength, hardness and durability of parts. Tests were carried out on 17-4PH stainless steel samples, both in the untreated state and after heat treatment, showing that the latter significantly increases hardness and improves overall mechanical properties. Microscopic observations...

Dieses Buch unterstreicht die Bedeutung von Nachbehandlungen zur Verbesserung der mechanischen Eigenschaften von Teilen, die mittels Laserschmelzen auf Pulverbett (SLM) hergestellt werden. Durch numerische Simulationen mit SIMUFACT Additive und experimentelle Studien wurde nachgewiesen, dass diese Behandlungen die Festigkeit, Härte und Haltbarkeit der Teile signifikant beeinflussen. Die Tests wurden an Proben aus rostfreiem Stahl 17-4PH im Rohzustand und nach der Wärmebehandlung durchgeführt und zeigten, dass letztere die Härte deutlich erhöht und die mechanischen Eigenschaften insgesamt...
