Structural Design Integrated Systems Health ManagementStructures How Would ISHM Impact the Following?: • Current Structural Design Philosophy • Reduce FOS? • Lighter Design? • New Structural Design Philosophy • Enable Reliability-based (Probabilistic) Design Approach? • Reduce reliance on structural redundancy for fail-safety, reduces weight and cost? • Structural/Materials Certification Process • Reduce Certification Time? • New Structural Maintenance Procedure • Enable Condition-Based Maintenance? Full-Scale Structural Fatigue Test Structural Inspection
Health Monitoring for Structural “Hot Spots” Application Design Initial Structural Design Identify High Stress areas Modify Initial System Design Design SHM System To determine health in those areas Subcomponent Design Fabrication Test (validation) Is SHM system >98% accurate ? No Identify barriers to obtain 98% accuracy Element Design Fabrication Test (validation) Element Yes Done!
