(Feb 28th) In this video lecture, Prof. Lisa Pruitt lectures on Fatigue Design.
Topics: Fatigue, Relevance in tissues and devices, failure modes, design philosophy, total life philosophy, stress based approach, S-N plot generation, strain based loading, cycling softening, strain based fatigue life
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.
