This symposium supported by the ASCE EMI Stability Committee is to provide a forum to discuss recent advances and address the future prospects in the area of instabilities that are either purely elastic in nature or those that lead to ultimate failure of structural components, systems and materials, in theoretical analysis, physical experiments and/or numerical simulation. Interested researchers are invited to submit abstracts on topics which include classical and non-classical instability problems that discuss failure caused by buckling or where instability is being used to enhance structural system or component performance.

Topics of Interest Include:

• Instability in columns, beams, plates, shells and sandwich structures made from metallic or composite materials
• Instability of structures with linear or nonlinear materials in the elastic or inelastic range
• Post-buckling analysis including analytical/computational modelling and methods
• Development and applications of numerical continuation and generalized path-following techniques
• Interactive buckling in slender structures; progressive cellular buckling and snaking
• Buckling across scales: nano, micro, thin film and lattice structures
• Adaptive, morphing and multistable structures; applications to design and smart structures
• Instability-driven failure of materials including cracks, delaminations and micro-buckling
• Orthotropic and anisotropic materials: related instability problems
• Dynamic stability problems including energy absorption systems or crashworthiness analysis
• Experimental techniques for structural and material stability tests
• Instabilities in layered and granular media including shear and kink band formation
• Non-local mechanics including instabilities in systems with non-local effects
