(Apr 4th) In this video lecture, Dr. Scott Robertson lectures on Fatigue, Fracture and LBL.
Stent Failure, failure analysis of biomedical devices, microscopy, sterilization, In Vivo failure mechanisms, explanted stent examinations, explant analysis, coronary stents, co-alloy SFA stent, crack growth mechanisms, high cycle fatigue, damage tolerance approach, flatened nitinol tube, load ratio, R-Ratio Significance, Fracture toughness, fatigue and design, overload fracture
This course of UC Berkeley - Bio Engineering/ME C117: Structural Aspects of Biomaterials - provides an overview of medical devices, FDA regulatory issues, biocompatibility and sterilization technology. It examines biomechanical properties: isotropy/anisotropy, stiffness, bending stresses, contact stresses, multiaxial loading, plasticity, fatigue, fracture, wear, corrosion, design issues. Also covered: Orthopedics, Dental, Cardiovascular, and Soft Tissue Reconstruction.Professor Pruitt's current research is focused on fatigue and fracture micromechanisms, cyclic damage zones, and evolution of structure due to cyclic loading and environment in advanced polymers and biomaterials.
