DescriptionThe degradation of a structure, under various loading conditions, involves the progress of damage by initiation and growth of defects, such as microvoids and microcracks, and their coalescence into macrocracks. This symposium provides a platform for structural and materials community to present recent advances in computation and experimentation of damage initiation and growth in metal alloys (wrought and additively manufactured) and composites. A particular focus will be put on the fatigue and fracture modeling, simulation and experimental characterization from micro to macroscale. Recent advances in computational modeling of fatigue and fracture such as phase field methods, crystal plasticity, peridynamics and microstructurally-based approaches are covered. Non-traditional methods to fatigue damage modeling such as data-driven methods, information theory based approaches and entropic methods are welcome.
Contributions are welcome on, but not limited to the following topics:
• The role of microstructure in fatigue crack initiation mechanisms
• Fatigue and fracture of additively manufactured metal alloys, effect of defects, heat treatment, etc.
• Multiaxial and spectrum loading fatigue
• Fatigue of composite materials
• Environmentally assisted cracking: Stress Corrosion Cracking, Corrosion-Fatigue, Pitting Corrosion
• Nondestructive damage assessment methods such as Infrared Thermography, Acoustic Emission, Ultrasonic, Digital Image Correlation, Fiber Optic, Vibration and etc.
• Computational modeling of fatigue and fracture: Fracture Mechanics, Continuum Damage Mechanics, Crystal Plasticity, Phase Field Models, Peridynamics, Entropic Method, Statistical Mechanics and Information Theory based Models
