Infrastructure performance is shaped by cumulative deterioration and environmental exposure.
DM2L advances multi-scale, mechanics-based life-cycle models that quantify fatigue, corrosion,
and fracture processes and integrate these mechanisms into reliability and durability-informed planning.
Core Research Focus
- Multi-scale fatigue and fracture modeling (micro/meso/macro)
- Corrosion-induced degradation and durability assessment
- Reliability-based life-cycle performance and uncertainty quantification
- Variable-amplitude loading and microstructure-sensitive damage evolution
- Maintenance, inspection, and rehabilitation strategy optimization
What Has Been Done
- Developed multi-scale fatigue damage frameworks and microstructure-sensitive crack growth estimation
- Advanced computational approaches for life-cycle damage quantification of infrastructure materials/details
- Integrated durability and reliability concepts for long-term performance assessment
What We Are Doing Now
- Coupling deterioration models with hazard-driven loading to assess performance under extreme events
- Developing scalable (physics + data) approaches for durability-informed reliability
- Linking life-cycle deterioration with system-level resilience planning
Strategic Plan
- Develop predictive life-cycle digital twin concepts for infrastructure durability
- Integrate deterioration with multi-hazard mechanics for realistic risk projections
- Enable reliability-based optimization for inspection and maintenance planning
- Connect component deterioration to network-level performance and resilience outcomes
How This Connects
Life-cycle damage mechanics provides the durability foundation for multi-hazard performance assessment and
strengthens reliability modeling for lifelines, interdependent networks, and community resilience planning.
