- RESEARCH AREAS AND APPLICATIONS
- 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 to
predict wear and damage of total joint
replacement components.
- Characterized the kinetics
- of fatigue crack growth
- of microcracks
- and of macrocracks
- in human cortical bone.
- Microcracks decelerate
- and arrest at
- microstructural
- barriers. Fatigue
- crack propagation
- resistance of
- macrocracks are
- reduced by age-related
- changes in bone
- tissue.
Fatigue crack growth of older female bone tissue
is less than younger female bone tissue.
Damage retrieved PE total knee and total hip
