  1. APPROACH • Static and cyclic mechanical testing measurements of smooth and notched specimens; constitutive modeling • Microstructural and ultrastructural damage identification measurements in bone using acoustic emission methodologies • Microstructural and ultrastructural characterizaton of materials using light, scanning and transmission electron microscopy; fourier transform infrared microspectroscopy • COLLABORATIONS • Departments of Orthopaedics and Neurosurgery, CWRU Medical School • Rush Presbyterian Medical School, Chicago, IL • Exponent Failure Analysis; Drexel University, Philadelphia, PA • The Hospital for Special Surgery; Cornell University Medical College, New York, NY • RESEARCH SPONSORS • NIH, OREF, Orthopaedic Industries CLARE M. RIMNAC EMAE ASSOCIATE PROFESSOR OF MECHANICAL & AEROSPACE ENGINEERING and Director, Musculosketeal Biomechanics and Orthopaedic Engineering Laboratories 620 GLENNAN BUILDING cmr10@po.cwru.edu; 216-368-6442; 216-368-3007 (fax) • RESEARCH AREAS AND APPLICATIONS • Mechanical performance of musculoskeletal tissues • Mechanical performance of orthopaedic implant materials • Modeling of musculoskeletal tissues and implant materials • Implant retrieval/failure analysis of total joint replacements • RECENT ACCOMPLISHMENTS • Identified material and sterilization factors affecting the static and cyclic fracture resistance and wear damage resistance of UHMW polyethylene joint replacement components through laboratory testing and implant retrieval/failure analysis • Retrieved total knee • replacement • Characterized the kinetics of fatigue crack growth of (short) microcracks in human cortical bone. Microcracks decelerate and arrest at microstructural barriers. • Fatigue crack growth of Microcracks in bone • microcracks in bone Taylor Prediction
