APPROACH
Mechanical testing of materials; physically-inspired constitutive
modeling of materials; finite element analyses of structures
Microstructural and ultrastructural identification of damage and
microstructural and ultrastructural characterization of materials
using light, scanning and transmission electron microscopy;
fourier transform infrared microspectroscopy
COLLABORATIONS
Mechanical performance and modeling of musculoskeletal
tissues
Mechanical performance and modeling of inert and resorbable
orthopaedic implant materials
Implant retrieval/failure analysis of total joint replacements
RECENT ACCOMPLISHMENTS
Developed physically-based constitutive models of conventional
and new crosslinked ultra high molecular weight polyethylene
formulations that predict fracture of total joint replacement
components.
