Craig Friedrich (ME-EM) presented two podium papers, “Enhanced Bone Fixation of TKA Tibial Tray Implants with TiO2 Nanotubes” and “In Vivo Anti-Bacterial Effectiveness of Nanotextured Titanium Implant Surfaces” at the 31st International Society for Technology in Arthroplasty (ISTA) Conference in London, England.

The conference, which addressed innovative solutions for arthroplasty, took place Oct. 10-13, 2018 at the Queen Elizabeth II Conference Centre. Established in 1988, ISTA is dedicated to advancing the art and science of technology in joint replacement by connecting the leading clinicians, engineers, researchers, and industry members from around the globe.

Extract

Improving the functionality of composite materials is a key requirement for various aerospace, auto-motive, sports and defense applications. The trend is to identify mechanisms, design, constituents, and, preferably, the combination of all of them that can result into better mechanical properties in the conflicting domain of interest (e.g. high stiffness and high damping or high stiffness and high toughness) without adding much complexity in the analysis and design.

The present work considered an “interconnected” geometry inspired by biological materials in a composite material made of very different material properties. Our computational study showed that the interconnection was effective in improving the load transfer between two dissimilar materials by the virtue of contact-friction mechanism, compared to layered materials.
