International Union of Theoretical and Applied Mechanics symposium 12-15 Feb

The University of Canterbury will host the IUTAM symposium on “Moving Boundary Problems in Mechanics” from 12-15 February 2018.

The mission of IUTAM – the International Union of Theoretical and Applied Mechanics – is to encourage the development and application of all branches of the science of mechanics throughout the world.

The symposium, co-chaired by Dr Stefanie Gutschmidt and Associate Professor  Mathieu Sellier of the Department of Mechanical Engineering, is the second symposium ever to be organized in New Zealand. It is an exciting opportunity to showcase the University of Canterbury new premises, in particular the newly built Engineering Core and lab facilities.

Approximately 60 international experts in applied mechanics, fluid mechanics, and engineering science from over 17 countries will gather to further develop analytical, experimental, and computational methods and push the boundaries of moving boundary problems in mechanics.

Understanding boundary problems

Many problems in mechanics involve deformable domains with moving boundaries.

  • An archetypical example would be how the sail of boat deforms in response to the wind to produce a resultant aerodynamic force. The complex fluid-structure interaction between the flowing air and the sail’s internal stress leads to given deformation of the sail.
  • Other examples include flows with a free surface, flows over soft tissues and textiles, flows involving accretion and erosion, flows through deformable porous media, material forming, shape optimization, to name but a few.

The interaction of the moving boundary with the participating media leads to fascinating phenomena in a broad range of contexts such as wing flutter, wave-breaking, sand dune formation, ripple formation on the ocean floor, flow instabilities, structure resonance and failure, atherosclerosis, ice formation on aircraft wings, etc .

Understanding this two-way interaction is a challenge of modern mechanics.
