Computational Problems in Materials Science - Part I of IV

10:00 AM-12:00 PM
Room: Independence A

For Parts II, III, and IV, see MS9, MS16, and MS23, respectively.

Scientific computing and numerical analysis have now become primary tools for studying the complex behavior exhibited during many physical processes in materials science. These processes are characterized by randomness, singularities, strong nonlinearity, nonconvexity, multiple constitutive components, and multiple spatial and temporal scales. During the last decade, many efficient numerical methods have been developed for many problems, including the determination of effective macroscopic material properties, mesoscopic simulations of microstructure development and evolution, and microscopic simulations of atomistic interactions. Improved algorithms and faster computers now make it possible to simulate many more complicated physical properties and processes than ever before. This trend will only accelerate in the future. The speakers in this minisymposium will focus primarily on numerical methods for continuum models of materials. They will also discuss methods based on atomistic models, and present applications to composite materials, shape-memory alloys, liquid crystals superconductors, and magnetic materials.
