The SDMoMS workshop provided a forum for exchange of ideas between the smart material modeling community and the design community. The possibility of a common modeling framework was explored to come up with modeling tools and to enable designers with exercising their choice of materials from an array of existing smart materials, gather material property data, and compare and simulate these materials in a relatively simple manner before arriving at an optimal design. The workshop focused on materials such as shape memory materials, magnetic solids and fluids, polymers for smart applications and ferroelectrics.
