Research Interests
Research Interests:
Fatigue, fatigue crack growth, fracture
Design and optimization of materials for fatigue and fatigue crack growth resistance.
Light metals (traditionally cast and semi-solid processed)
Advanced microstructure characterization and microstructure-performance relationships optimization
Physical metallurgy aspects of solidification processes of cast alloys
Impact of post-solidification operations (heat treatment) on mechanical properties, fatigue, fatigue crack growth.
Alloy/process development from fundamentals to production
Traditional and novel techniques to measure residual stress and new methods to compensate for its presence
Evaluate plasticity contributions to fatigue crack growth and fracture toughness and introduce elastic/plastic growth analyses
Closure and long-crack to small-crack correlations in fatigue crack growth
Fracture mechanics concepts and their application to residual stress and crack closure corrections
"On-line" residual stress, plasticity, and closure corrections techniques
Develop appropriate/compatible fatigue life prediction models
Powder metallurgy
Novel, forensic, and historic materials
