Extreme events that occur as the result of manmade and natural disasters (blast, impact and penetration, earthquake, tsunami, landslide, etc.) pose severe threats to our society's well-being. Development of computational methods to predict and understand these complex events is of significant importance. Research in this area is a timely topic, and also crucial for safeguarding the manmade and natural environments.

This session aims to promote collaboration among academia, government, and industry in the development and application of advanced computational methods for the simulation and study of extreme events. Those in the related fields of computational solid mechanics, fluid dynamics and fluid-structure interaction, and other related computational fields for analysis of disasters are cordially invited to exchange their ideas and research results in this Minisymposium. This Minisymposium will solicit all subjects related to development and application of computational methods for extreme events, which include, but are not limited to, the following:

• Recent advances in computational methods for the simulation of problems involving harsh dynamic loadings, high strain-rates, large material distortion, fracture and failure, contact and impact, or fragmentation
• Recent advances in methods and algorithms for treating stationary and transient strong and weak discontinuities (shocks, shear bands, fracture)
• Fluid-structure interaction for disaster dynamics and material/structure failure
• Multiscale approaches to extreme material failure and disaster simulation
• Constitutive modeling and materials characterization of materials under high strain rate
• Simulation of multi-phase (solid, fluid, gas) interaction in disaster events
• Applications of computational methods to simulation of natural disasters like tsunamis, earthquakes, and landslides
• Applications of computational methods to simulation of manmade disasters like blast and penetration
• Computational investigations on infrastructure resiliency
• Computational investigations on high-rate damage and failure mechanisms in ductile, brittle and quasi-brittle materials and structures
• Computational investigations of failure of geo-materials and structures
• Disaster simulations involving multiple and coupled physics
• Disaster simulations involving multiple time and/or length scales
• Verification and validation of disaster simulation models
• Large scale parallel computation and scalable algorithms for extreme event simulation
