Paragraph starter

The selection of materials for prosthetic components is critical for ensuring both functional performance and long-term durability. Research indicates that advanced composites, such as those incorporating carbon and glass fibers, offer high tensile strength (e.g., 162 MPa) and stiffness (e.g., 2 GPa), making them suitable for prosthetic feet. Similarly, specialized alloys like Ti-13Nb-13Zr demonstrate exceptional yield strength (470 MPa) and ultimate tensile strength (558 MPa), ideal for implant components. Furthermore, understanding material behavior under cyclic loading through fatigue testing is essential for predicting component lifespan and preventing failure in real-world use.
